TRAXXAS UNLIMITED DESERT RACER rear drive shaft stainless steel 304+aluminum by GPM UDR237S  [UDR237S]

Rear drive shaft upgrade for TRAXXAS

This is an RC-scale rear drive shaft assembly intended for the TRAXXAS UNLIMITED DESERT RACER platform, supplied by GPM as model UDR237S. The set replaces the center-to-rear drivetrain link and transfers torque from the center gearbox to the rear differential.

Construction details provided by the source indicate the axle joint pieces use stainless steel 304 for corrosion resistance, while the shaft body integrates aluminum sections to balance weight and rigidity. The shaft is described as slightly thicker than the original to increase transmission durability under typical RC desert and off‑road loads. Silicon O‑rings are fitted at the axle joint interface to reduce direct metal‑to‑metal contact and to cushion impacts to the CVD during landings.

Installation notes: the set is presented as a direct replacement for the center rear drive connection and includes fasteners for mounting. Check CVD spline engagement and driveline alignment during installation, verify O‑ring seating, and ensure the shaft clears suspension travel to avoid binding. Regular inspection of the O‑rings and joint fitment is recommended after heavy landings.

Use this assembly when you need a stiffer rear driveline component for RC desert or off‑road running; it serves as a straightforward replacement part that prioritizes joint durability and reduced wear at the CVD interface while keeping installation and maintenance simple.
