Description

The Traxxas 3942X is a 12-tooth pinion gear with a 32-pitch. It is machined from hardened steel for durability and features a 3mm bore to fit motor shafts.

This gear is a direct bolt-on for Traxxas vehicles that use 32-pitch gearing. Swapping pinion tooth count is an easy way to adjust your vehicle's gear ratio, with more teeth increasing top speed and fewer teeth increasing acceleration and torque.
