GPM WW2238C Rear CVD Shaft 38mm Technical Upgrade by GPM  [WW2238C]

Precision rear CVD shaft for WR-02 service

This aftermarket rear CVD shaft is a purpose-built replacement intended for the Tamiya 1/10 Wild Willy 2 WR-02 platform. Machined for consistent geometry, the 38mm steel component supports routine maintenance and drivetrain rebuilds where a direct-fit, high-strength shaft is required.

Functionally, the shaft transmits rotational force from the gearbox output to the rear differential while accommodating suspension articulation. Confirm spline engagement depth and the 38mm specification align with the WR-02 coupling to ensure correct installation and effective torque transfer.

Installation procedure: disassemble the rear CVD/dogbone assembly, inspect spline surfaces and retaining hardware, and fit the new shaft using appropriate threadlocker and torque settings. After assembly, verify driveline angles and rotate joints by hand to check for free running and correct clearance.

For technical-minded hobbyists seeking a robust, repeatable replacement shaft for WR-02 drivetrains, this GPM steel CVD provides predictable fitment and service life advantages in demanding use cases.
