TRAXXAS Unlimited Desert Racer Rear Ring & Pinion Upgrade - UDR1200S by GPM  [UDR1200S]

Rear differential replacement for UDR

This RC replacement gear set is produced for the TRAXXAS Unlimited Desert Racer rear differential case. The parts use hardened steel #45 to cope with repeated loads in the rear gearbox while remaining focused on correct fitment and function.

The set reduces clearance between mating gears to improve engagement consistency and to help smooth power transfer under normal RC conditions. It is supplied as a 6pcs kit that includes the ring gear, pinion gear, and the flat head screws needed to fit the gears in the rear differential area.

When installing these gears inspect gear mesh and axial play, replace bearings if necessary, and tighten screws to the vehicle manufacturer's torque recommendations. Correct mesh and secure fastening will support consistent operation of the hardened steel gears without claiming extra performance benefits.

A straightforward direct-fit replacement for enthusiasts seeking a hardened steel ring and pinion set to suit the UDR rear differential case, supplied with the required mounting screws.
