Traxxas 12-T 48-Pitch 3mm Shaft RC Pinion Gear - 2428

The Traxxas 2428 is a 12-tooth, 48-pitch pinion gear designed to fit motors with a 3mm shaft, making it a direct-fit replacement or gearing option for compatible Traxxas RC models. Part number TRX2428, it includes a set screw for secure shaft retention. Pinion gears are a core part of your drivetrain's gear ratio, and swapping to a different tooth count lets you tune acceleration or top speed to suit different driving conditions. The 48-pitch specification means it must be paired with a 48-pitch spur gear — mixing pitches will damage both gears.
