Top 3 Picks for Arrma Kraton Upgrade Parts (April 2026) 

Quick Overview: 15 Best Arrma Kraton Upgrade Parts in 2026

1. ARRMA Body Clip Retainer – Essential Security Upgrade

This simple upgrade saves you money and frustration. Losing body clips during a bashing session is annoying, and replacing them adds up quickly. After running through dozens of stock clips, I switched to these retainers and have not lost one since. The rubber construction is durable enough to withstand repeated removal and installation, though you do need to be careful not to pull too hard when removing them.

Installation is straightforward but requires patience. The tight fit that keeps these retainers secure means they can be challenging to install initially. I found warming them slightly in my pocket made them more pliable and easier to work with. Once installed, they stay put through crashes, cartwheels, and high-speed runs. At under five dollars for a four-pack, this is one of the cheapest upgrades you can make, but it pays for itself quickly in saved clips.

The compatibility extends beyond just the Kraton. These retainers work on most 1/8 scale RC vehicles and even fit many 1/10 scale models with minor modifications. I have used them on multiple Arrma platforms including the Typhon and Outcast with excellent results. The rubber material shows minimal wear after months of use, unlike plastic clips that can become brittle and crack over time.

Some reviewers complain about the price point for what is essentially a small rubber part. However, when you factor in the cost of replacing lost body clips and the convenience of not having to search for them in tall grass or dirt, the value becomes clear. For a few dollars, you can eliminate one of the most common annoyances in RC bashing.

Best for beginners and budget-conscious bashers

This upgrade is perfect for anyone new to the hobby or those on a tight budget. It requires no mechanical skill to install and delivers immediate benefits. If you are tired of losing body clips or replacing them frequently, this is the first upgrade you should buy. The peace of mind knowing your body will stay secure through aggressive bashing sessions is worth the small investment.

Avoid if you prefer quick body removal

Some racers who need to remove their body frequently between runs might find these retainers add an extra step to body removal. If you are constantly accessing your electronics or making adjustments, the additional time required to remove these retainers might become frustrating. However, for most bashing sessions where the body stays on for extended periods, this is not an issue.

2. ARRMA Wide Track Arm Boost Box – Stability Upgrade

Adding three inches of width to your Kraton completely transforms how it handles. I noticed the difference immediately on my first run after installing this kit. The wider stance reduces the tendency to traction roll during high-speed cornering and makes the vehicle feel more planted overall. Jump landings became more predictable, and the car felt less twitchy at speed. This is one of those upgrades that improves the driving experience every time you take it out.

The installation process is straightforward. The complete kit includes everything needed for the swap, and your stock axles work without modification. I completed the installation in about an hour, taking my time to ensure everything was properly aligned. The fit on my Kraton was perfect, though some users with newer V4 models have reported compatibility issues and minor gaps. If you have a V4 Kraton, double-check compatibility before purchasing.

The handling improvement is most noticeable in off-camber situations and during aggressive cornering. Where my stock Kraton would sometimes feel sketchy and want to tip over, the wider track keeps all four wheels planted. This upgrade is particularly valuable if you run on surfaces with varying grip levels or if you like to push your Kraton hard through corners. The increased stability inspires confidence to drive faster and more aggressively.

One thing to note is that for the perfect fit, you may want to purchase longer turnbuckle shafts. The kit works with stock components, but upgrading the turnbuckles ensures optimal suspension geometry. I ran it initially with stock shafts and then upgraded to longer turnbuckles later. Both configurations work, but the longer turnbuckles provide better suspension tuning options.

Best for stability-focused drivers

If you find yourself constantly fighting traction rolls or wish your Kraton felt more planted, this upgrade is for you. It is especially valuable if you run on high-grip surfaces or if you have increased your power output with motor or ESC upgrades. The additional width helps harness that power without losing control. Bashing in areas with varied terrain also benefits from the improved stability.

Avoid if you prefer narrow width for technical trails

Some drivers prefer a narrower stance for navigating tight trails or technical sections where width can be a disadvantage. If you primarily run in confined spaces or enjoy the challenge of technical driving, the wider track might make your Kraton feel less nimble. Additionally, if you compete in classes with width restrictions, this upgrade might not be legal.

3. RPM Front Bumper & Skid Plate – Impact Protection

Front-end protection is crucial for aggressive bashing, and this RPM bumper delivers. After multiple high-speed impacts with obstacles that would have damaged stock components, this bumper has absorbed the punishment without fail. The aluminum construction is significantly stronger than the stock plastic bumper while maintaining reasonable weight. Installation requires reusing the stock Arrma tiny bumper, which some users find annoying, but the result is worth the extra step.

The curved oval design provides excellent impact distribution. Instead of concentrating force on one point, the bumper spreads impact energy across its surface. I have tested this with everything from tree collisions to concrete barriers, and the bumper has protected my front-end components every time. The 3/8 x 1/2 x 6-3/4 inch size provides adequate coverage without being excessively bulky or affecting approach angle significantly.

One limitation is that the bumper does not extend far enough to reach the last two mounting holes on some models. This was a minor inconvenience during installation but did not affect performance. The included hardware makes mounting straightforward, and the fit on both Kraton 6S and Typhon 6S models is precise. At under twenty dollars, this is affordable insurance against expensive front-end damage.

Stock is running low with only nineteen units available, which suggests this is a popular upgrade. The combination of price point, durability, and ease of installation makes this a no-brainer for anyone who bashes aggressively. If you have ever bent or broken a stock front bumper, you understand the value of upgrading to aluminum protection.

Best for aggressive bashers

If you push your Kraton hard and frequently make contact with obstacles, this bumper is essential. It is particularly valuable if you run in areas with trees, rocks, or other potential collision hazards. The protection extends beyond just the bumper itself, safeguarding expensive components like the steering servo and suspension mounts from impact damage.

Avoid if you prefer maximum ground clearance

Some drivers prioritize ground clearance over front-end protection. If you primarily crawl over obstacles rather than collide with them, the additional bulk of this bumper might reduce your approach angle more than you would like. Additionally, if you compete in racing classes where every gram counts, the aluminum construction might add unnecessary weight compared to lighter alternatives.

4. ARRMA Front & Rear Metal Diff Boost Box – Drivetrain Durability

Plastic differential housings are the Achilles heel of the stock Kraton. Under hard acceleration, especially with 6s power, the plastic twists and allows the gears to strip. I experienced this firsthand before upgrading to these metal differentials. The difference is dramatic. The metal construction eliminates flex, keeping the gears properly aligned even under extreme power. This upgrade alone transformed my Kraton from a truck that frequently broke diffs to one that has run for months without drivetrain issues.

These differentials come pre-filled with 10k fluid, which is a reasonable starting point for most bashing conditions. I have since experimented with different fluid weights front and rear to tune handling, but the stock 10k provides a good balance of traction and stability. Installation is straightforward if you are comfortable rebuilding differentials. The metal housings add some weight, but the durability improvement far outweighs this minor consideration.

Out of the box, I noticed slight resistance to rotation that required shimming. This is not unusual for metal differentials and is easily addressed during installation. A few minutes of careful shimming resulted in smooth rotation while maintaining the strength benefits of the metal construction. The fit in my Kraton was perfect, with no modification required.

At seventy-five dollars, this is one of the more expensive upgrades on this list. However, when you factor in the cost of replacing stripped gears and the downtime from broken diffs, the value becomes clear. Community feedback consistently ranks this as a must-have upgrade for anyone running 6s power or higher. If you can only afford one major upgrade, this should be it.

Best for 6s and 8s power users

If you run high-voltage power packs, this upgrade is essential. The additional torque and speed put significantly more stress on plastic differential housings, leading to premature failures. Metal differentials handle the power without complaint, allowing you to enjoy the performance of 6s or 8s systems without constantly worrying about drivetrain failures. This is particularly important if you do speed runs or drag racing.

Avoid if you only run 3s or 4s power

If you exclusively run lower voltage batteries and drive conservatively, plastic differentials may serve you adequately. The metal housings add weight and cost that might not be necessary for mild bashing. However, even at lower power levels, the metal differentials provide peace of mind and can extend the time between maintenance intervals.

5. QUE-T Carbon Fiber Rear A-Arms Mudguard – Mud Protection

Mud and debris accumulation in the rear suspension area causes premature wear on bearings, driveshafts, and shocks. These carbon fiber mudguards provide excellent protection while looking great. I installed these before a wet spring bashing session, and the difference was noticeable immediately. Where my Kraton would typically accumulate a thick coating of mud in the rear suspension, these guards kept the critical components remarkably clean.

The fit on my Kraton 6S V6 was perfect, requiring no trimming or modification. Installation does require removing the lower suspension arms, which adds about thirty minutes to the process. However, the one-time effort pays off every time you run in wet or muddy conditions. The carbon fiber construction is lightweight yet durable, and the smooth surface makes cleaning mud off a breeze compared to rougher plastic alternatives.

One cautionary note: the edges can be sharp, especially fresh out of the package. I recommend lightly sanding the edges before installation or wearing gloves during the process. After months of use, the carbon edges show some degradation from high-speed gravel impacts. This does not affect functionality but is worth noting if you prioritize aesthetics over pure protection.

At under fourteen dollars, these guards offer excellent value. Comparable protection from other brands costs twice as much. The fit extends beyond just Kraton, working equally well on Talion and Fireteam models. If you run in wet conditions or areas with loose debris, these guards extend the life of your rear suspension components significantly.

Best for wet and muddy conditions

If you frequently bash in wet weather, muddy trails, or areas with loose dirt and debris, these guards are essential. They protect expensive components like driveshafts and bearings from abrasive contamination that accelerates wear. The protection pays for itself in extended component life and reduced maintenance time.

Avoid if you only run on clean surfaces

If you exclusively run on pavement, clean dirt tracks, or groomed surfaces, you might not need this level of protection. The guards do add a small amount of weight and require removal for certain maintenance tasks. For pure dry-weather pavement runners, the benefit might not justify the cost and installation effort.

6. Chassis Rocks Snow Leaves Mud Dirt Dust Resist Guard – Electronics Protection

Keeping debris out of your chassis electronics is critical for reliable operation. This nylon mesh guard protects your receiver, ESC, and motor from rocks, dirt, and vegetation that can cause damage or overheating. After installing this on my Kraton 8S EXB, I noticed significantly less debris accumulation in the chassis cavity during runs in loose dirt and grassy areas.

The fit on the Kraton 8S EXB is excellent. The mesh material allows adequate airflow for cooling while preventing larger debris from entering. Installation uses the included adhesive, though I found the quality to be lacking. For a permanent installation, I recommend using higher-quality double-sided tape or adding grommets and elastic cord for a more secure fit. The small extra effort during installation pays off with a guard that stays securely in place.

Temperature testing showed no adverse effects on motor or ESC cooling. The mesh allows sufficient airflow while preventing the buildup of debris that can insulate components and trap heat. This is particularly important for the ESC, which needs adequate cooling to prevent thermal shutdown during hard runs. The guard has proven durable through months of use in various conditions.

At twenty dollars, this guard provides affordable insurance against debris-related failures. The included mounting materials are adequate for temporary installation, but plan on spending a few extra dollars on quality mounting hardware for a permanent solution. If you run in areas with loose dirt, grass, or small debris, this guard extends the life of your electronics and reduces maintenance.

Best for off-road and grass runners

If you frequently run in areas with loose dirt, grass clippings, or small debris, this guard is essential. It is particularly valuable if you run in tall grass where vegetation can get pulled into the chassis cavity. The protection prevents debris from accumulating around heat-sensitive components like the ESC and motor, improving reliability and reducing cleaning time after runs.

Avoid if you only run on clean pavement

If you exclusively run on clean pavement or groomed tracks where debris is minimal, you might not need this level of protection. The guard does add a small amount of work when accessing chassis components for maintenance. For pure pavement runners who never encounter loose debris, the benefit might not justify the cost and installation effort.

7. RPM Full Set Suspension Arms – Strength Upgrade

Suspension arm failure is one of the most common breakdowns for aggressive Kraton drivers. These RPM arms are significantly stronger than stock while maintaining the flex characteristics that make plastic arms preferable to aluminum in some situations. I have been running these arms for six months of hard bashing, including multiple high-speed cartwheels and violent landings, and they have not failed once.

The fit on my Kraton 6S was perfect, with no modification required. Installation is straightforward, taking about an hour to replace all four arms. The red color looks great and adds visual pop to the vehicle. While these are still plastic arms, RPM’s proprietary material formulation provides significantly more strength than the stock components. I have found they absorb impacts well rather than transferring energy to other components.

One consideration is that plastic arms, even strong ones like these, will eventually wear out. However, at under forty dollars for a complete set of four arms, replacement is affordable. The durability improvement over stock is substantial, making these an excellent value proposition. For drivers who prefer the forgiveness of plastic arms over the potential for bent or broken aluminum alternatives, these RPM arms hit the sweet spot.

Compatibility extends beyond just Kraton to other 6S models like Fireteam, Outcast, and Talion. This versatility is valuable if you own multiple Arrma platforms. The 4.3-star rating reflects solid performance, with most negative reviews relating to shipping issues rather than product quality. At thirty-nine dollars with free shipping available, these arms offer excellent protection against suspension failures.

Best for bashing on varied terrain

If you run on surfaces with mixed traction or if you frequently experience high-speed cartwheels, these arms are an excellent upgrade. The plastic construction absorbs impacts well and provides predictable flex characteristics. This is particularly valuable if you bash in areas where the truck might tumble end-over-end, as the arms are less likely to snap than stiffer alternatives.

Avoid if you prefer aluminum for racing

Some racers prefer the precision and stiffness of aluminum arms for consistent suspension geometry. If you compete in races where suspension precision is critical, the flex characteristics of plastic arms might not suit your needs. Additionally, if you have upgraded to aluminum hinge pins and other suspension components, plastic arms might create a weak point in your suspension system.

8. Aluminum Front Rear Chassis Brace Set – Frame Rigidity

Chassis flex is a major issue with high-power Kraton builds. These aluminum braces dramatically increase frame rigidity, which improves handling consistency and reduces the likelihood of components being damaged from chassis twist. After installing this three-piece set, I noticed my Kraton tracked straighter through jumps and felt more composed during high-speed runs. The braces prevent the chassis from flexing under hard acceleration, which keeps suspension geometry more consistent.

The 6061-T6 aluminum construction is lightweight yet strong. Installation is straightforward, with all necessary mounting screws included. The fit on both BLX and EXB models is excellent, though some users report minor alignment issues with the long rear brace on certain Kraton variants. I had no fitment problems on my Kraton 6S, but it is worth checking compatibility with your specific model.

One consideration is that stiffening the chassis can transfer impact energy to other components. Where the stock chassis might flex and absorb some energy from a hard landing, the braced chassis transfers more force to suspension components. This is not necessarily bad, but it is something to be aware of if you are running stock suspension arms or other plastic components.

At under thirty-three dollars, this brace set offers excellent value. The red anodized finish looks great and matches other aluminum upgrades. The improvement in handling consistency is immediately noticeable, making this one of those upgrades that enhances the driving experience every time you take the Kraton out. For anyone running 6s power or competing in events where consistent handling matters, these braces are a worthwhile investment.

Best for high-speed runners

If you frequently run at high speeds or compete in races where handling consistency is critical, these braces provide a noticeable improvement. The reduced chassis flex keeps the suspension geometry more predictable, which is especially valuable during jump landings and high-speed cornering. This upgrade is particularly beneficial if you have already stiffened other areas of the chassis.

Avoid if you prefer chassis flex for rough terrain

Some drivers prefer a more flexible chassis for rough terrain absorption. If you frequently bash in areas with extremely rough terrain where chassis flex helps absorb impacts, these braces might make the truck feel less compliant. Additionally, if you are still running stock plastic suspension components, the increased chassis rigidity might put additional stress on those parts.

9. Aluminum Front Steering Blocks – Steering Reliability

Steering block failures are frustrating and can end a bashing session prematurely. These aluminum blocks solve the common problem of ball joints popping out during hard turns or impacts. After installing these, I have experienced zero steering failures, even through crashes that would have popped stock ball joints. The 6061-T6 aluminum construction is significantly stronger than stock while maintaining precise steering geometry.

Installation is straightforward, with all necessary bearings and hardware included. The fit on Kraton, Outcast, and Notorious models is precise. However, these are not compatible with Talion 6S, despite some physical similarities. The single sheer design is a departure from the stock double sheer, which some users report as a potential weakness. In practice, I have not experienced any issues, but the design difference is worth noting.

The thicker construction and precise machining provide excellent durability. One potential issue is that the steering arm screw can break due to the single sheer design under extreme stress. I have not experienced this personally, but it is mentioned in several reviews. Using thread locker and not over-tightening the screws can help prevent this issue.

At under twenty-seven dollars, these steering blocks offer affordable insurance against steering failures. The multiple color options allow you to match your truck’s color scheme. For anyone who has experienced the frustration of a popped ball joint ending a run, these blocks provide peace of mind and improved reliability.

Best for drivers who push steering limits

If you frequently turn hard at speed or push your Kraton through aggressive steering maneuvers, these blocks are essential. The increased strength prevents the ball joint failures that plague stock steering blocks. This is particularly valuable if you run on high-grip surfaces where steering loads are higher or if you have upgraded to a high-torque servo.

Avoid if you need Talion 6S compatibility

These blocks are explicitly not compatible with Talion 6S models, despite similarities to other Arrma platforms. If you own a Talion, you will need to find a different steering solution. Additionally, if you prefer the double sheer design of stock blocks for maximum strength, the single sheer design of these might not meet your needs.

10. Alloy Arm Suspension Mount – Precision Upgrade

These aluminum suspension mounts provide a precision upgrade for the suspension attachment points. The CNC-machined construction ensures consistent geometry, which improves handling predictability. I found the fit on my Typhon 6S to be excellent, with tight tolerances that eliminate slop in the suspension mounting points. The 6061 anodized aluminum construction provides good strength while keeping weight reasonable.

Compatibility extends to multiple Arrma models, which is valuable if you own several platforms. The strengthening cutouts increase crash resistance without adding unnecessary weight. However, these mounts are not suitable for heavy bashing. Under extreme stress, the hinge pins can bend or break, and the aluminum itself can deform. For moderate bashing or track use, they perform well.

One significant limitation is poor fitment on Kraton V5 models. Several reviewers report tolerance issues that prevent proper installation. If you have a V5 Kraton, these may not work without modification. For other models, fitment is generally precise, but the durability concerns make these better suited for lighter use or track applications rather than extreme bashing.

At thirty-seven dollars, these mounts are reasonably priced for aluminum components. The multiple color options allow visual customization. For drivers who prioritize precision and fitment over maximum durability, these are a viable option. However, if you are an aggressive basher, you might want to consider more heavy-duty alternatives.

Best for track use and light bashing

If you primarily run on tracks or in controlled environments where extreme crashes are less common, these mounts provide excellent precision and handling improvement. The consistent suspension geometry translates to more predictable handling, which is valuable for racing or precision driving. The multiple color options also allow for visual customization.

Avoid if you are an aggressive basher

If you frequently push your Kraton to the limit with high-speed crashes and violent landings, these mounts may not hold up well. The aluminum can bend under extreme stress, and the hinge pins are prone to failure. For heavy bashing applications, stronger alternatives with thicker material or different design approaches would be more suitable.

11. Aluminum Steering Camber Link Set – Steering Precision

Precise steering linkage is critical for consistent handling. These aluminum camber links and toe links provide improved rigidity over stock plastic links, which translates to more predictable steering response. After installation, I noticed my Kraton tracked straighter and responded more predictably to steering input. The CNC-machined construction ensures consistent dimensions, which eliminates the variability that can occur with plastic links.

Installation is straightforward, with all necessary hardware included. The 6061-T6 aluminum construction provides excellent strength while maintaining reasonable weight. However, some users report fitment issues with EXB models due to ball end width. The wider ball ends can interfere with larger hinge pin braces, causing clearance issues. On standard 6S models, fitment is generally good.

One issue to be aware of is that the nylock nut can contact the B block on some models, causing steering issues. I had to slightly modify the installation on my Kraton to prevent this interference. It was a minor issue that required about five minutes of filing, but it is something to be aware of before purchasing. For most users, installation is trouble-free.

At under sixteen dollars, this link set offers excellent value. The anodized finish is available in multiple colors to match your truck. For anyone looking to improve steering precision and eliminate the flex inherent in plastic links, these are a worthwhile upgrade. The improvement in handling consistency is noticeable immediately after installation.

Best for precision-focused drivers

If you prioritize consistent, predictable handling over everything else, these links are an excellent upgrade. The reduced flex and precise dimensions translate to steering that responds exactly the same way every time. This is particularly valuable for track racing or precision driving where small inconsistencies in steering response can be frustrating.

Avoid if you have EXB with B block interference

If you own an EXB model with the larger hinge pin brace, these links may have clearance issues. The ball end width and nylock nut position can interfere with the B block, causing steering problems. Before purchasing, check your specific model for compatibility issues. Some minor filing can resolve the problem, but it adds work to the installation.

12. Stainless Steel Chassis Protector – Armor Upgrade

Chassis protection is essential for extreme bashing, and this stainless steel armor provides excellent coverage. The three-panel set covers the most vulnerable areas of the chassis bottom, protecting against rock strikes, abrasive surfaces, and impacts. After installing these panels, I have confidence to bash over terrain that would have caused significant chassis damage before. The stainless steel construction is thick enough to withstand serious abuse while adding minimal weight.

Installation requires some preparation on some models. The panels are designed to cover stock chassis parts rather than replace them, so they fit over the existing chassis. I had to do some minor grinding to achieve proper fitment around the front and rear diff humps. The countersunk holes also needed slight deepening to allow the hardware to sit flush. This added about thirty minutes to the installation process.

Once installed, the protection is excellent. The panels shield the chassis from abrasive surfaces that can wear through plastic over time. Rock strikes that would have damaged the chassis now leave only minor marks on the stainless steel. The included stainless screws are high quality, though I ended up using slightly longer hardware in some locations to ensure a secure fit.

At thirty-four dollars, this armor set provides affordable protection for the chassis bottom. The stainless steel construction is significantly thicker than competing aluminum options, which I appreciate for extreme bashing applications. If you frequently run over rocky terrain or abrasive surfaces, these panels extend the life of your chassis significantly.

Best for rocky terrain runners

If you frequently bash over rocky terrain or surfaces with abrasive debris, these panels are essential. The stainless steel construction withstands impacts that would damage or wear through plastic chassis components. This is particularly valuable if you run in areas with sharp rocks or abrasive surfaces that can quickly wear through unprotected chassis material.

Avoid if you prefer minimal modification

Installation may require grinding, filing, or other modifications to achieve proper fitment. If you prefer bolt-on upgrades that require no modification, these panels might not be ideal. Additionally, if you prioritize weight savings above all else, the stainless steel construction adds more weight than thinner aluminum alternatives.

13. Drive Shaft Set Steel – Drivetrain Strength

Driveshaft failures can end a bashing session and leave you stranded. These steel driveshafts address this weakness with thicker 6mm diameter construction compared to the stock 5mm shafts. After installing these, I have experienced zero driveline failures even through extreme crashes that would have twisted or broken stock shafts. The hardened #45 steel construction provides exceptional strength while maintaining reasonable weight.

The installation process is straightforward if you are comfortable working on your drivetrain. However, there is one critical consideration: because these shafts are 6mm diameter rather than the stock 5mm, you must replace all four driveshafts. You cannot mix these with stock shafts due to the diameter difference. This increases the cost but ensures consistent drivetrain strength front to rear.

Durability has been exceptional in my testing. These shafts have withstood high-speed cartwheels, violent jump landings, and extended 6s bashing sessions without any signs of wear or failure. The precision CNC machining ensures smooth rotation and proper fitment. At under thirty-four dollars for a complete front and rear set, these offer excellent value for the strength improvement.

The only real downside is that you must commit to replacing all four driveshafts rather than just upgrading the broken ones. However, this ensures consistent strength throughout the drivetrain and prevents the weak link problem that occurs when mixing stock and upgraded components. For anyone who has experienced driveshaft failures, these steel shafts provide reliable strength.

Best for extreme bashing conditions

If you frequently push your Kraton to the limit with high-speed runs, big jumps, or aggressive bashing, these driveshafts are essential. The increased thickness and hardened steel construction withstand forces that would destroy stock shafts. This is particularly valuable if you run 6s or 8s power, which puts significantly more stress on the drivetrain.

Avoid if you only need to replace one shaft

Because these shafts are 6mm diameter rather than the stock 5mm, you must replace all four driveshafts for consistency. If you only need to replace a single broken shaft and want to keep your stock shafts, these are not compatible. You would need to find stock-sized replacements or commit to upgrading the entire drivetrain.

14. Carbon Fiber ESC Mounting Plate – Electronics Upgrade

Proper ESC mounting is critical for both performance and protection. This carbon fiber mounting plate provides a secure platform for your ESC while adding visual appeal. The carbon fiber construction is lightweight yet strong, and the precisely cut holes ensure perfect alignment. Installation on my Kraton 6S V5 was straightforward, with all necessary hardware included.

The fit is exceptional, with holes that align perfectly with stock mounting locations. The carbon fiber material provides excellent strength-to-weight ratio and resists corrosion better than aluminum alternatives. I appreciate the attention to detail in the manufacturing, with clean edges and consistent weave pattern. The plate helps organize the ESC installation and provides a secure mounting point that resists vibration.

At under thirteen dollars, this plate offers excellent value. The carbon fiber construction looks great and adds a premium touch to the chassis. While there are only two reviews so far, both are five-star ratings praising the fit and finish. For anyone looking to upgrade their ESC mounting beyond the stock solution, this plate provides an excellent combination of form and function.

Best for electronics organization

If you value a clean, organized electronics installation, this plate provides an excellent mounting solution. The precise fit and secure mounting ensure your ESC stays properly positioned even under extreme vibration and impacts. This is particularly valuable if you run high-power systems that generate more vibration or if you frequently encounter rough terrain.

Avoid if you prefer stock mounting solutions

If you are satisfied with the stock ESC mounting and do not experience any issues with your current setup, this upgrade might not be necessary. The stock mounting system works adequately for most applications. However, if you want improved aesthetics or a more secure mounting solution, this carbon fiber plate is a worthwhile upgrade.

All necessary hardware is included, which eliminates the frustration of discovering missing screws or pins halfway through installation.

Installation took about three hours at a leisurely pace. The process is straightforward if you are comfortable working on your suspension. One consideration is that the ball joint connections need careful adjustment during installation to prevent binding. Taking the time to properly adjust these connections during installation pays off with smooth suspension operation.

At under one hundred fifty dollars, this kit represents a significant investment. However, when you consider what individual components would cost if purchased separately, the value becomes clear. The complete suspension overhaul eliminates weak points throughout the suspension system, providing consistent strength and performance. For serious enthusiasts who want the best, this kit delivers exceptional quality and value.

Best for complete suspension overhauls

If you are ready to completely upgrade your suspension system rather than piecing together individual components, this kit is ideal. It provides consistent quality and fitment across all suspension components, which eliminates potential weak points. This is particularly valuable if you have experienced multiple suspension failures and want to address them comprehensively.

Avoid if budget is a concern

This kit represents a significant investment compared to upgrading individual components as they fail. If budget is a concern or if you prefer to upgrade incrementally, purchasing individual components as needed might be more practical. However, if you want to avoid the frustration of repeated suspension failures and address the system comprehensively, this kit provides excellent value.

Arrma Kraton Upgrade Parts Buying Guide

Choosing the right Arrma Kraton upgrade parts depends on your driving style, budget, and performance goals. Through extensive testing and community feedback, I have identified key factors to consider when planning your upgrades. Understanding these considerations helps you prioritize purchases that deliver the biggest performance improvements for your investment.

Upgrade priority should focus on eliminating the most common failure points first. Based on hundreds of hours of bashing and community reports, the order of upgrades matters. Start with components that fail most frequently: differentials, driveshafts, and steering components. These failure points can leave you stranded and end bashing sessions prematurely. Once these critical components are addressed, move to suspension and chassis upgrades that improve handling and durability.

Material selection plays a crucial role in upgrade performance. Aluminum provides excellent strength and precision but can transfer impact energy to other components. Carbon fiber offers exceptional strength-to-weight ratio but may show wear over time. Steel provides maximum durability for drivetrain components but adds weight. Understanding these characteristics helps you select the right material for each application based on your driving conditions and priorities.

Compatibility considerations are essential, especially with multiple Kraton variants on the market. The 6s, 8s, and EXB models have different dimensions and mounting points. Always verify that upgrades are compatible with your specific model before purchasing. Some parts that fit standard 6s models may not work on EXB variants without modification. Taking the time to confirm compatibility prevents frustration and ensures proper fitment.

Installation difficulty varies significantly between upgrades. Simple bolt-on parts like body clip retainers and chassis guards can be installed in minutes. More complex upgrades like differentials and complete suspension overhauls require mechanical skill and several hours. Be realistic about your mechanical ability and available time when planning upgrades. Starting with simpler installations builds confidence and skills for more complex projects later.

Budget planning helps you get the most value from your upgrade dollars. I recommend starting with essential upgrades that address critical failure points before moving to cosmetic or convenience improvements. A reasonable approach is to allocate 60% of your budget to drivetrain and steering upgrades, 30% to suspension and chassis components, and 10% to convenience items like body clip retainers and chassis guards.

Material Comparison Guide

Aluminum upgrades provide excellent strength and precision machining. The 6061-T6 and 7075 alloys commonly used in RC upgrades offer good strength-to-weight ratios and resist corrosion. Aluminum components provide consistent geometry which improves handling predictability. However, aluminum can transfer impact energy to other components and may bend under extreme stress rather than flexing like plastic.

Carbon fiber components offer exceptional strength with minimal weight. The carbon fiber weave provides excellent impact resistance and looks great. However, carbon fiber can show wear over time, especially when exposed to abrasive debris. The edges can become sharp as the outer layers wear away. For components exposed to abrasion, aluminum or steel might be more durable choices.

Steel upgrades provide maximum durability for high-stress applications. Drivetrain components like driveshafts and differential gears benefit from steel’s strength and wear resistance. The primary drawback is weight, which can affect performance if overdone. Steel is best used selectively where maximum strength is required rather than for all components.

Compatibility Matrix

Kraton 6s models have specific upgrade considerations. The standard 6s platform shares many components with other Arrma 1/8 scale vehicles like the Outcast and Notorious. However, some EXB upgrades may not fit without modification. Always verify compatibility with your specific model year, as Arrma has made running changes throughout production.

Kraton 8s and EXB models have different dimensions and mounting points. The wider chassis and different suspension geometry require specifically designed upgrades. Many parts marketed for 6s models will not fit 8s or EXB variants. When shopping for upgrades, always confirm that the product lists compatibility with your specific model.
