TRAXXAS TRX4 Trail Pinion 13T Hardened Steel TRX4013T by GPM  [TRX4013T]

13T Hardened Pinion for TRX4 Trail Use

This aftermarket 2pcs pinion gear set is intended for TRAXXAS TRX4 Trail Crawler scale models and is sold as an RC accessory. Each gear is turned from hardened steel #45 to withstand load-related wear, and the pack includes one 3x3 screw shaft for fixing the pinion to the motor shaft.

Made to replace the stock pinion or serve as an upgrade, the 13T 32-pitch gear allows you to alter overall gearing for improved crawling torque without changing the spur. Manufacturer-provided dimensions to check before purchase are a centre bore of 3.175mm, tooth spacing of 0.8mm, and 13 teeth matching 32-pitch spur gears commonly used on TRX4 rigs. This steel option is recommended for repeat slow-speed contact where longevity is the priority.

Fitment notes: slide the pinion onto the motor shaft, set correct mesh with the spur, and secure with the supplied 3x3 screw shaft. Double-check backlash and confirm both pinion and spur are 32-pitch to avoid accelerated wear.
