This aluminum rear axle hub set is an aftermarket replacement part produced by GPM for the Traxxas Unlimited Desert Racer (UDR) platform. It serves two practical functions: to stabilise the rear axle for smoother rotation and to provide a secure mounting point for the brake disc caliper.
The kit is intended as a scale RC accessory for maintenance or modest upgrades to axle mounting and brake assembly stability. Installation requires basic disassembly of the rear hub area and standard hand tools; check existing fastener layout and torque settings on your UDR when refitting.
Use this set to replace worn rear hub components or to restore proper brake caliper alignment on a Traxxas UDR chassis.
