GPM TRAXXAS MAXX 18T Hardened Steel Motor Pinion TXMS018TS - RC Spare Part  [TXMS018TS]

18T motor pinion built for TRAXXAS MAXX

This hardened steel #45 motor gear is a direct replacement engineered to mate with the motor output on TRAXXAS MAXX monster truck models. It transmits torque from the motor to the drivetrain and helps preserve consistent engagement between the motor pinion and the mating gear under load.

Fitment is mechanical: slide the gear onto the motor shaft, set a safe mesh clearance, and secure the set screw to hold position. The steel construction improves wear resistance compared with softer materials, helping maintain dependable gear engagement during tuning and regular running.

Installation tips: ensure mating surfaces are clean, align teeth so contact is even across the face, and perform an initial low-throttle run to confirm smooth rotation and no binding before full use.
