Traxxas 15-T 1.0 Metric Pitch 5mm Shaft RC Pinion Gear - 6487X

The Traxxas 6487X is a 15-tooth pinion gear with a 1.0 metric pitch, designed to fit motors with a 5mm output shaft across a range of Traxxas RC vehicles. Supplied with a set screw for secure fitment, this pinion gear is a direct replacement for worn or damaged gears in the drivetrain. Swapping the pinion is one of the most effective ways to adjust your gearing ratio — a smaller pinion lowers top speed for more torque, while a larger one raises top speed at the cost of acceleration. The TRX6487X gives you a factory-spec 15T option for maintaining or restoring the stock gear ratio.
