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

UDR rear gearbox pinion

Designed for the TRAXXAS UNLIMITED DESERT RACER UDR platform, this aftermarket rear differential pinion carries the model number UDR1200S/G2. It is intended as a drop-in replacement inside the rear gearbox to refresh or upgrade the differential assembly.

Materials and purpose: the pinion is made from hardened steel #45 to give improved wear resistance over common stock gears, and the profile reduces backlash to promote smoother engagement and longer component life under typical off-road use.

Included items: one pinion gear and four stainless steel flat head screws 2.5x8 are supplied to match the gearbox mounting arrangement.

Fitting advice: install into the rear gearbox as the differential pinion, tighten the supplied screws, then rotate the assembly by hand to verify mesh before applying power to the model.
