GPM TRAXXAS UDR Differential Ring Gear Hardened Steel #45 UDR1200S/G1 - RC Spare Part  [UDR1200S/G1]

UDR front and rear ring gear upgrade

This UDR1200S/G1 ring gear from GPM is a scale replacement made for the TRAXXAS UNLIMITED DESERT RACER drivetrain. It fits into the front or rear gearbox and transmits torque from the bevel pinions into the differential carrier.

Manufactured from hardened steel #45, the part offers stronger wear resistance than standard steel gears. The tougher alloy and tighter production tolerances help to reduce gear gap and backlash, producing a steadier mesh and more consistent power transfer under load.

Fit this ring gear as a direct replacement or when you want to firm up drivetrain feel and longevity. Always confirm tooth count and physical fit before fitting, then set gear mesh and check differential play after assembly to avoid premature wear.

A practical, scale-minded replacement aimed at improving engagement and durability in the TRAXXAS UDR front or rear gearbox; verify mesh and fit during installation for the best results.
