Traxxas 18-T Machined 1.0 Metric Pitch 5mm Shaft RC Pinion Gear - 6491X

The Traxxas TRX6491X is a machined 18-tooth pinion gear designed for Traxxas RC drivetrain applications requiring a 1.0 metric pitch gear and a 5mm motor shaft. Precision-machined rather than stamped, this pinion gear offers tighter tolerances than a standard replacement, making it a solid choice when rebuilding or servicing the drivetrain on compatible Traxxas models. It ships with a set screw for secure shaft fitment.
