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

Replacement gears for UDR rear case

This replacement gear set is intended for use in the TRAXXAS Unlimited Desert Racer rear differential case. Components are hardened steel #45 to withstand repetitive gearbox loads while focusing on accurate fit and reliable service life.

The design reduces backlash between mating gears to promote steadier engagement and smoother torque transfer during typical RC driving. Supplied as a 6pcs set, the kit contains the ring gear, pinion gear, and the four flat head screws required for installation in the rear differential area.

When installing, inspect and set gear mesh and axial clearance, renew bearings where needed, and torque screws to the vehicle manufacturer's values. Proper setup and secure fastenings will help the hardened steel gears behave consistently without asserting specific speed or power gains.

A no-nonsense replacement option for hobbyists wanting a direct-fit hardened steel ring and pinion set for the UDR rear differential case, complete with mounting screws.
