Traxxas 26-Tooth 32-Pitch 3mm Bore RC Pinion Gear - 5645

The Traxxas 5645 is a 26-tooth, 32-pitch pinion gear with a 3 mm bore, designed as a direct-fit replacement or gearing option for compatible Traxxas models. Pinion gears are a key part of the drivetrain, sitting on the motor shaft and meshing with the spur gear to transfer power to the wheels. Swapping to a different tooth count lets you adjust your final drive ratio — a higher tooth count raises top speed, while a lower count increases low-end acceleration and reduces motor temperatures under load. The TRX5645 is a genuine Traxxas part, ensuring correct pitch and bore dimensions for a clean mesh with your existing spur gear.
