TRAXXAS UNLIMITED DESERT RACER Center front hardened steel drive shaft by GPM UDR037SF  [UDR037SF]

Center front drive shaft overview

This GPM aftermarket center front drive shaft is an RC-scale replacement part designed for the TRAXXAS UNLIMITED DESERT RACER platform and identified by part code UDR037SF.

Constructed from hardened steel #45, the shaft is machined with a slightly increased diameter compared with the stock unit to improve bending resistance and transmission stiffness while remaining suitable for hobby-grade drivetrain loads.

Functionally the shaft transfers rotational power from the front gearbox to the front differential and wheels, and its role in setup and tuning is to provide a more consistent drivetrain response under load, which helps when adjusting gear ratios, motor output, or suspension settings.

Installation notes: the part fits into the standard center front output location and is secured with the supplied screw; basic disassembly of the front gearbox is required and common hand tools for hobby cars are sufficient.

Use this shaft when replacing worn center front components or when seeking a slightly stiffer drivetrain feel; verify fitment before final installation and torque fasteners to hobby-standard values.
