SCX10 III Upgrade Buying Guide – What to Buy First?

After testing all these Axial SCX10 III upgrade parts and talking with fellow crawlers in the community, I’ve developed a clear upgrade priority guide. The question I hear most often is “what should I upgrade first on my SCX10 III?” The answer depends on your budget and driving style, but there’s a general order that makes sense for most owners.

First priority is always the servo. The stock SCX10 III servo is weak and prone to stripping gears, which will leave you stranded on the trail. Any of the four servos covered in this guide will be a massive improvement, with the ANNIMOS 20KG offering the best balance of performance and value for most owners. A stronger servo not only improves steering capability but also increases your enjoyment of the vehicle.

Second priority is wheels and tires. The stock SCX10 III tires are capable but leave significant room for improvement. The Hobbypark combo gives you both wheels and tires in one affordable package, while the RCLIONS beadlocks let you keep your existing tires if you prefer. The difference in traction between stock and aftermarket tires is often the single biggest performance gain you’ll experience.

Third priority depends on your driving style. Technical crawlers should look at portal axles next, with the Treal axles being worth the premium for serious owners. Faster trail runners might benefit more from the motor/ESC upgrades, with the RCenjoy brushless combo providing smooth, controllable power that inspires confidence on difficult terrain.

Fourth priority is suspension components. The INJORA shocks provide both performance and appearance benefits, with the 120mm version for front and 100mm for rear giving your SCX10 III properly balanced suspension action. Better shocks help your tires maintain contact with irregular surfaces, which improves traction and control.

For SCX10 III Base Camp owners, the priority order remains similar but with extra attention to the servo and tires first. Base Camp models benefit from the same upgrades as Coyote versions, though some owners choose to stop after the first two or three priority items rather than pursuing a full build.
