Traxxas Ring & Pinion Front RC Differential Gear - 8978

The Traxxas TRX8978 ring gear and pinion gear set is a direct-fit front differential replacement for select Traxxas models, restoring drivetrain performance when worn or damaged gears cause slipping, noise, or loss of drive. These two gears work together inside the front differential housing to transfer power to the front axles, making this a functional repair part rather than an optional upgrade. If you're rebuilding a front differential on a compatible Traxxas vehicle, TRX8978 gives you the correct OEM-spec gears to get it back running properly.
