Traxxas 12-T 32-P with Set Screw RC Pinion Gear - 3919

The Traxxas TRX3919 is a 12-tooth, 32-pitch pinion gear designed as a direct-fit spare part for a wide range of Traxxas RC models. This small-diameter RC pinion gear sits on the motor shaft and meshes with the spur gear to transfer power through the drivetrain, making it a core component whenever you're rebuilding or servicing the gearbox. It ships with a set screw for secure motor shaft mounting.

Key Features

• 12-tooth, 32-pitch specification — match both figures to your existing spur gear before fitting
• Set screw included for firm, rattle-free mounting on the motor shaft
• Direct Traxxas spare part, designed to OEM dimensions for the compatible model range
• Suited to drivetrain rebuilds, routine maintenance, or replacing a stripped or worn pinion
