GPM Racing Aluminium Rear Axle Housing (Without Carrier) - 23pcs Set for Traxxas 1/7 Unlimited Desert Racer-85076-4 (UDR013B)

High precision rear axle housing for TRAXXAS UNLIMITED DESERT RACER

This aluminium rear axle housing is supplied as an aftermarket replacement for TRAXXAS UNLIMITED DESERT RACER models under model UDR013B. The assembly replaces the stock rear axle housing (without carrier) and is delivered as a 23pcs set including the stainless steel fasteners required for proper installation.

CNC machined from aluminium 6061 T6 in a one-piece configuration, the housing provides accurate bores and mating faces to reduce drivetrain backlash and enhance rotational smoothness of the differential and shafts. The alloy construction improves tensile performance and heat transfer compared with polymer housings, aiding long-term dimensional stability under load.

Mounting is achieved using the included stainless steel round head screws; the retainers and washers included follow the counts shown in the packing includes section. Prior to final torqueing, verify alignment with suspension mounts and gearbox interfaces to ensure correct driveline geometry and prevent binding.

Specifications

• Item: Rear Axle Housing (Without Carrier), 23 pcs
• Material: Aluminium 6061 T6
• Model Number: GPM UDR013B
• Compatibility: TRAXXAS UNLIMITED DESERT RACER
• Manufacture: CNC machined one-piece design

Engineered for hobbyists prioritising precision and durability in UDR drivetrains, this CNC one-piece aluminium housing should be test-fitted and aligned carefully to achieve the intended reduction in drivetrain play.

What material and process are used to make the housing?

The housing is CNC machined from aluminium 6061 T6 as a one-piece component to achieve consistent bores and mounting surfaces for improved dimensional accuracy.

Does this housing include the carrier or internal differential parts?

This listing covers the rear axle housing only and does not include the carrier or differential internals; those components must be sourced separately if required.

How does the one-piece CNC design benefit drivetrain performance?

A one-piece CNC aluminium housing reduces assembly variability and surface deformation under load, which helps maintain alignment and reduce play between axle and differential components. Write Product Review Please sign in your account before you can write any review. Sign In Close
