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

14T Replacement Pinion for TRAXXAS TRX4

This aftermarket 14T steel pinion set is intended for TRAXXAS TRX4 trail crawlers, coupling directly to the motor shaft and transferring torque into the spur gear and drivetrain. The twin-pack format gives a spare or a matched pair for both sides of a build.

Confirmed attributes include hardened steel #45 material, 14 tooth count, centre bore 3.175mm, 0.8mm tooth spacing and pitch 32. The kit contains a 3x3 screw shaft to hold the pinion on the motor. Always match these specs to your existing spur and motor shaft prior to purchase or installation.

Fitment pointers: ensure the motor shaft is 3.175mm, set correct mesh to avoid gear binding, and tighten the screw to stop slippage while avoiding damage to the motor shaft. Selecting different tooth counts will modify the drive ratio and change torque versus top speed tradeoffs.
