TRAXXAS UNLIMITED DESERT RACER Harden Steel #45 Front/Rear Differential Ring Gear by GPM UDR1200S/G1  [UDR1200S/G1]

Differential ring gear for UDR

This GPM UDR1200S/G1 ring gear is an RC-scale replacement designed for the TRAXXAS UNLIMITED DESERT RACER drivetrain. It installs inside the front or rear gearbox where the differential ring gear sits and serves to carry torque between the bevel pinions and the differential assembly.

The part is made from hardened steel #45 to provide increased wear resistance compared with standard steel gears. The harder material and tighter manufacturing tolerances are intended to reduce gear gap and backlash, which helps the gearset run with steadier mesh and more consistent power transfer under load.

Use this part when you need a direct replacement or when tuning drivetrain feel and durability. Confirm tooth count and fitment against your existing ring gear before installation, and check gear mesh and differential play after assembly to avoid premature wear.

This gear set is a straightforward, scale RC replacement aimed at improving gear engagement and component longevity in the TRAXXAS UDR front or rear gearbox; verify fitment and mesh during installation for best results.
