This 14T steel motor pinion is supplied as a single piece for Axial EXO vehicles and serves as a direct replacement or an upgrade for adjusting gear ratio on electric rock racers.
Installation note: fit the pinion to the motor output shaft, verify shaft diameter and spline match, then set and secure the spur gear mesh using your motor mount fasteners. Check mesh and fixings again after an initial short run.
Tuning note: reducing or increasing pinion teeth changes the motor RPM and torque at the wheels; this 14T option favours stronger low speed torque for technical rock crawling and torque-centric setups.
