31-Tooth Pinion Gear (48-Pitch) 3 mm Bore

Compatible with most Traxxas electric models featuring 3 mm motor shafts. The 31-tooth configuration delivers a balanced gear ratio suitable for mixed terrain and moderate speed runs. Set screw included for secure shaft mounting. Experiment with different pinion tooth counts to dial in acceleration versus top-end speed based on your driving style and track conditions. Higher tooth counts increase top speed; lower counts boost acceleration. Stock recommendation varies by model—check your manual for baseline gearing before making adjustments.

Fits Traxxas Slash, Stampede, Rustler, Bandit, and other 2WD/4WD models equipped with 3 mm motor shafts. Also compatible with select Traxxas touring cars and buggies using standard brushed or brushless motors with 3 mm bores. Always verify your specific model's motor shaft diameter and pinion compatibility in your owner's manual before purchase. When in doubt, contact Traxxas support or your local hobby shop for confirmation.
