This aluminium rear axle hub set is an aftermarket replacement part from GPM made for the Traxxas Unlimited Desert Racer (UDR). It improves rear axle support for more even wheel rotation and gives a solid fixing point for the brake caliper.
The kit is aimed at scale maintenance or modest performance-minded upgrades to axle mounting and brake stability. Fitting involves basic rear hub disassembly and standard hand tools; double-check fastener placement and torque when reinstalling on your UDR chassis.
Use the set to replace worn hubs and to realign the brake caliper mounting on a Traxxas UDR for steadier rear-end performance.
