TRAXXAS UNLIMITED DESERT RACER Rear Drive Shaft UDR237S by GPM  [UDR237S]

Rear driveline replacement for TRAXXAS race rigs

This rear drive shaft assembly is made for the TRAXXAS UNLIMITED DESERT RACER and carries the model UDR237S. It replaces the centre-to-rear connection to move torque from the centre gearbox to the rear differential while aiming for improved durability over the stock shaft.

Construction combines stainless steel 304 at the axle joint surfaces with aluminium sections along the shaft to balance strength and weight. The shaft body is a touch thicker than standard to resist wear under desert and off-road loads. Silicon O-rings sit at the joint interface to reduce metal-on-metal contact and to cushion the constant-velocity drive during hard landings.

Fitting notes: this set is supplied as a direct rear driveline replacement and includes the mounting fasteners. During installation check spline engagement, align the driveline to prevent binding, confirm O-ring seating, and make sure the shaft clears full suspension travel. Inspect O-rings and joint fit after heavy impacts to maintain reliable operation.

Choose this assembly when you want a stiffer rear driveline for desert and off-road running; it is a simple replacement that prioritises joint longevity and lower wear at the CVD interface while keeping maintenance straightforward.
