TRAXXAS UNLIMITED DESERT RACER Rear Pinion Hardened Steel #45 UDR1200S/G2 by GPM  [UDR1200S/G2]

Precision rear pinion for UDR drivetrains

This replacement rear differential pinion is specified for the TRAXXAS UNLIMITED DESERT RACER UDR platform and carries model number UDR1200S/G2. It is intended for installation within the rear gearbox as a direct swap to the factory pinion to improve engagement stability.

Material and function: produced in hardened steel #45 to provide elevated wear resistance, the component reduces backlash by tightening tooth clearance which results in smoother gear meshing and more predictable load transfer through the differential.

Package contents: one hardened steel pinion and four stainless steel flat head screws 2.5x8 are supplied to match the standard rear gearbox mounting configuration.

Installation notes: install into the rear gearbox as the differential pinion, use the supplied screws, manually verify mesh and rotation prior to applying motor power, and inspect after initial running for correct seating and secure fastenings.
