Traxxas 15T 32-Pitch Heavy Duty Machined Hardened Steel 3mm Shaft RC Pinion Gear - 3945X

The Traxxas 3945X is a 15-tooth, 32-pitch pinion gear machined from hardened steel and designed to fit 3mm motor shafts across a wide range of Traxxas RC vehicles. Supplied with a set screw for secure installation, this heavy duty RC pinion gear is a direct replacement for worn or damaged units in the Traxxas drivetrain. If you're rebuilding a gearbox, replacing a stripped pinion, or re-gearing for a different speed and torque balance, the TRX3945X is the correct factory-spec part to use.
