TRAXXAS TRX4 Hardened 14T Pinion TRX4014T by GPM  [TRX4014T]

Hardened 14T Pinion for TRAXXAS TRX4 Drive

This pair of 14-tooth steel pinions is offered as an aftermarket upgrade for TRAXXAS TRX4 trail rigs, designed to sit on the motor shaft and mesh with the spur gear to deliver power to the driveline. The set is aimed at rock crawling and heavy use where durability is important.

Reported dimensions and materials: hardened steel #45, 14 teeth, centre bore 3.175mm to match common motor shafts, 0.8mm tooth spacing and pitch 32. A 3x3 securing screw is included in the set to lock the pinion in place. Verify these measurements against your existing gearset before fitting to ensure compatibility.

Fitting advice: check the shaft diameter against the 3.175mm bore, adjust the mesh with the spur gear to prevent binding or excess wear, and secure the pinion with appropriate torque. Swapping tooth counts will alter gearing, so choose a pinion that suits your terrain and motor characteristics.
