Traxxas Rear Differential Ring and Pinion Gears

The Traxxas Rear Differential Ring and Pinion Gears are designed to restore the rear planetary differential with the correct ring and pinion gear set for the assembly. When the original gears are worn or damaged, this replacement set gives you the parts needed to rebuild the rear differential with the proper tooth count and gear mesh.

This compact gear set uses a 47-tooth ring gear and a 12-tooth input gear. That pairing is what allows the rear differential to operate as intended inside the drivetrain, and it keeps the repair focused on the rear planetary differential without replacing more than necessary. The pinion gear also carries an important limitation: it is not compatible with the optional center differential or with the slipper clutch.

Why Choose This Product

The Traxxas Rear Differential gear set is a practical way to bring the rear planetary differential back to its intended gear engagement after wear or impact damage. Because the set pairs the ring and pinion gears together, it supports a complete rear differential rebuild with the correct parts in place. For owners maintaining their own Traxxas drivetrain, that makes the repair focused and direct while staying centered on the rear assembly itself.

Choose this product when the rear differential gears need to be replaced and you want the exact 47-tooth and 12-tooth gear pairing used in the supported rear drivetrain setup. The result is a clean repair for the rear planetary differential, with the important compatibility note kept in mind for the pinion gear.
