TRAXXAS TRX4 13T Steel Pinion for Low Speed Torque TRX4013T by GPM  [TRX4013T]

13T Steel Pinion for TRX4 Trail Crawlers

This 2pcs aftermarket pinion gear set is intended for TRAXXAS TRX4 Trail Crawler scale models as an upgrade part. Each gear is turned from hardened steel #45 for improved surface life under crawling loads, and the kit includes a 3x3 screw shaft to fasten the pinion to the motor shaft.

As a direct replacement or upgrade to the stock pinion, the 13-tooth 32-pitch gear lets you alter final gearing for better low-speed control without changing the spur. Manufacturer-supplied measurements to confirm fit are a center bore of 3.175mm, tooth spacing of 0.8mm, and 13 teeth matching 32-pitch spur gears found in TRX4 setups. Use this steel set where repeated low-speed contact durability is the priority.

Fitting tips: slide the pinion onto the motor shaft, set the mesh with the spur gear, then lock in place with the supplied 3x3 screw shaft. Recheck backlash and ensure both gears use 32-pitch specification to avoid accelerated wear.
