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

Rear differential upgrade for UDR

This is an RC-scale replacement gear set designed for the TRAXXAS Unlimited Desert Racer rear differential case. The set uses hardened steel #45 components intended to withstand repetitive loads inside the rear gearbox while keeping the description focused on part function and fit.

The kit reduces clearance between mating gears to promote steadier engagement and smoother power transfer under typical RC driving conditions. It is supplied as a 6pcs set made up of the ring gear, pinion gear, and the required flat head screws for installation in the rear differential area.

When fitting these gears, inspect gear mesh and axial play, re-use or replace bearings as needed, and torque the screws to the vehicle manufacturer’s recommendations. Proper mesh and secure fastening will help the hardened steel gears perform consistently without implying specific performance gains.

A straightforward replacement geared toward racers and hobbyists who want a direct-fit hardened steel ring and pinion set for the UDR rear differential case, supplied with the mounting screws required for assembly.
