This aluminum rear axle hub set is an aftermarket replacement produced by GPM for the Traxxas Unlimited Desert Racer (UDR) platform. It helps stabilise the rear axle for smoother rotation and provides a firm mounting point for the brake disc caliper.
The kit suits scale maintenance and modest upgrades to axle support and brake assembly stability. Installation requires basic disassembly of the rear hub area and common hand tools; verify fastener positions and correct torque on your UDR during refit.
Replace worn rear hubs with this set to restore correct brake caliper alignment and reduce axle play on a Traxxas UDR chassis.
