TRAXXAS TRX4 15T Hardened Steel Pinion for Crawling TRX4015T by GPM  [TRX4015T]

Hardened 15T pinion built for TRX4 crawling

This GPM TRX4015T 15T pinion gear is produced for use on the TRAXXAS TRX4 Trail Crawler chassis and is supplied as a pair to cover replacements or gear changes. The gears are cut to a 32 pitch with 0.8mm tooth spacing so they mate correctly with standard TRX4-compatible spur gears used in scale crawlers.

Key construction details come from the part data: hardened steel #45 material for better wear life, a centre bore of 3.175mm to suit common motor shafts, and a 15-tooth profile. The pack also contains one 3x3 screw shaft (1 pc) for securing the pinion in place when needed.

Practical setup advice: confirm your motor shaft diameter and spur gear pitch before fitting, set a correct gear mesh to prevent premature wear, and pick 15T when looking for stronger low-speed torque for technical obstacles rather than higher top speed. Product intended for scale RC use only.
