TRAXXAS UNLIMITED DESERT RACER Centre/Rear Hardened Steel Planetary Housing UDR035S by GPM  [UDR035S]

Technical overview of centre and rear planetary housings

This aftermarket assembly replaces the centre and rear planetary gear housings on the TRAXXAS UNLIMITED DESERT RACER chassis. The housings are precision-machined from hardened steel #45 to deliver reduced flex and a firmer seating surface for the planetary gear assemblies, improving mechanical stability under load.

The kit is supplied as a 7pcs set and includes the housings plus the stainless steel screws required for reassembly. Components are dimensioned for direct fit into the factory locations for the centre and rear planetary gear assemblies and are compatible with the stock planetary components used on the UNLIMITED DESERT RACER.

As a chassis-level upgrade, this part reduces unwanted axial and radial movement in the planetary stack, aiding in smoother rotation and more consistent torque transfer through the drivetrain. It is intended for hobbyists seeking improved mechanical rigidity or replacing fatigued housings, and it interfaces with the vehicle's existing planetary gears and fasteners.

Use this direct-fit hardened steel housing kit to minimise housing deformation and maintain planetary gear alignment on the UNLIMITED DESERT RACER chassis.
