TRAXXAS Unlimited Desert Racer 4140 Carbon Steel Rear Center Driveshaft by GPM UDR237SN/V1  [UDR237SN/V1]

Rear Center Driveshaft for TRAXXAS 1/7 UDR

This GPM aftermarket rear center driveshaft is made for TRAXXAS 1/7 Unlimited Desert Racer platforms and serves as a direct replacement for factory part number 8555 on RC-scale models. Fabricated from 4140 medium carbon steel, the shaft is intended to give a robust option for the centre rear driveline in off‑road scale use without altering the vehicle layout.

Design notes from the source include a dogbone thickness of 6 mm which increases resistance to twisting under load compared to thinner stock dogbones. The item installs in the rear drive shaft area and uses standard mounting hardware included in the package to secure the shaft to the driveline assembly.

Use this part when replacing a worn or damaged centre driveshaft or when seeking a stronger steel alternative for durability under frequent high‑load running. Keep setup and alignment unchanged from stock unless other drivetrain components are modified.

A straightforward steel replacement for the rear centre driveline on TRAXXAS 1/7 Unlimited Desert Racer RC models, chosen for repair or increased drivetrain toughness without further drivetrain redesign.
