Traxxas 18-T 32-P Heavy Duty Machined Hardened Steel 3mm Shaft RC Pinion Gear - 3948X

The Traxxas TRX3948X is an 18-tooth, 32-pitch pinion gear machined from hardened steel, designed as a heavy-duty drivetrain component for Traxxas RC models running a 3mm motor shaft. The included set screw secures the gear firmly to the motor shaft, making this a straightforward drop-in part when servicing or rebuilding your drivetrain. Compared to standard pinion gears, the machined hardened steel construction offers greater durability under sustained load, which is relevant when running higher-powered setups or in demanding conditions.
