Compatibility Notes

This 20-tooth pinion suits a broad range of crawler platforms and is handy for hobbyists looking to tweak torque versus top speed on mixed terrain. The tooth count offers subtle tuning without overhauling the setup.

Installation Advice

Ensure the 3Racing 20T pinion meshes cleanly with the spur and check for correct backlash after installation. Simple maintenance checks will extend the part life and keep your crawler handling as expected.

Can I use this pinion for rock crawling?

Yes, the 3RACING CRA-112 20T is well suited to rock crawling where slow, controlled torque is preferred over high top speed.

Should I change pinion after gearbox work?

After gearbox service, verify pinion alignment and inspect teeth for any damage; replacing the pinion is a good idea if wear is visible.

Is any shimming required?

Some setups need a small shim adjustment to achieve ideal mesh. Check contact pattern and add shims if you see edge loading on the teeth.
