TRAXXAS MAXX 18T Motor Pinion Hardened Steel TXMS018TS by GPM  [TXMS018TS]

Replacement 18T motor pinion for TRAXXAS MAXX

This hardened steel #45 18-tooth motor pinion is manufactured as a replacement to interface with the motor output on TRAXXAS MAXX monster truck models. It transfers torque into the driveline while helping to maintain correct mesh between the motor pinion and mating gear when under load.

Installation is straightforward: position the gear on the motor shaft, set the mesh to a safe clearance, and secure the set screw to retain the gear. The steel material increases wear resistance versus softer materials, supporting more consistent engagement during tuning and aggressive running.

Before first use, clean contact surfaces, align the tooth faces for even wear, and carry out a slow initial run to check for smooth rotation and absence of binding.
