TRAXXAS UDR Ring Gear Replacement Hardened Steel #45 UDR1200S/G1 by GPM  [UDR1200S/G1]

Replacement ring gear for TRX UDR

The UDR1200S/G1 ring from GPM is built as a scale replacement part for the TRAXXAS UNLIMITED DESERT RACER driveline. It installs in the front or rear gearbox to carry torque from the bevel pinions into the differential unit.

Made from hardened steel #45, this ring gear improves wear resistance over standard steel components. The increased material hardness and closer manufacturing tolerances aim to reduce backlash and maintain a steadier gear mesh under load.

Use this component when you need a direct swap or when tuning drivetrain feel and longevity. Double-check the tooth count and dimensions against your existing gear before fitting, and set mesh and differential play carefully after assembly to prevent premature wear.

A straightforward scale replacement that helps firm up gear engagement and extend component life in TRAXXAS UDR gearboxes; always verify fitment and mesh during installation.
