Traxxas 13-T 0.8 Metric Pitch 5mm Shaft RC Pinion Gear - 5642

The Traxxas TRX5642 is a 13-tooth pinion gear designed for Traxxas RC models using a 5mm motor shaft, spec'd at 0.8 metric pitch and cross-compatible with 32-pitch gear systems. It pairs with a set screw for secure shaft retention, making it a precise fit for Traxxas vehicles across multiple platforms. If you're replacing a worn pinion or adjusting your final drive ratio, this is the correct OEM-spec part for compatible Traxxas builds.
