Traxxas 19T 32P Heavy Duty Machined Hardened Steel RC Pinion Gear - 3949X

The Traxxas TRX3949X is a 19-tooth, 32-pitch pinion gear machined from hardened steel and designed to fit 3mm motor shafts across a wide range of Traxxas vehicles. As a heavy-duty RC pinion gear, it is a direct-fit replacement for the standard pinion on compatible Traxxas models and is secured via a set screw for a reliable hold on the motor shaft. The machined hardened steel construction makes this RC drivetrain part notably more durable than standard sintered options, making it well suited to regular bashing or extended run sessions where drivetrain wear is a concern.
