Traxxas 15T 32P with Set Screw RC Pinion Gear - 3917

The Traxxas 3917 is a 15-tooth, 32-pitch pinion gear designed as a direct-fit replacement or gearing option for a wide range of Traxxas electric RC models. Supplied with a set screw for secure motor shaft fitment, TRX3917 is a genuine Traxxas spare part that slots straight into the drivetrain without modification. Swapping pinion gears is one of the most effective ways to tune the gear ratio on your Traxxas model — a smaller pinion like this 15T unit prioritises torque and acceleration over top speed, making it a practical choice for bashing, off-road running, or situations where motor temperatures are running high.

Key Features

• Includes a set screw for solid, rattle-free attachment to the motor shaft
• Genuine Traxxas replacement part, manufactured to OEM dimensions for precise mesh with compatible spur gears
• Smaller tooth count compared to higher-T pinions reduces top speed and increases torque, useful for technical terrain or high-load bashing
