TRAXXAS TRX4 Trail Crawler 15T Steel Pinion Gear by GPM TRX4015T  [TRX4015T]

15T steel pinion for TRX4 trail crawler

This is a GPM TRX4015T 15T pinion gear produced for the TRAXXAS TRX4 Trail Crawler platform, supplied as a 2 pcs set for common replacement or gearing swaps. The pinions are machined with a 32 pitch and 0.8mm tooth spacing to match standard TRX4-compatible spurs used in scale crawling setups.

Material and basic dimensions are taken from the part data: hardened steel #45 construction for improved wear resistance, a center bore of 3.175mm for standard motor shafts, and 15 teeth. The set also includes one 3×3 screw shaft (1 pc) for securing the pinion to the motor when applicable.

Practical notes for installation and tuning: confirm your motor shaft diameter and spur gear pitch before fitting, retain correct mesh to avoid premature wear, and use the 15T choice when you want a lower-speed, higher-torque setup suitable for technical crawling rather than top speed. The component is sized for RC scale use only.
