Traxxas Ring & Pinion Rear RC Differential Gear - 8977

The Traxxas TRX8977 ring gear and pinion gear differential set is a direct-fit rear differential replacement for compatible Traxxas models. These gears sit at the heart of the rear differential, transferring drive torque to the rear axles and allowing each wheel to rotate at different speeds through corners. Keeping this component in good condition is essential to maintaining traction and drivetrain efficiency, and having a genuine Traxxas spare on hand means less time waiting for parts when you need to get back on the track or bash site.
