TRAXXAS TRX4 Trail Crawler Screw Pins for F/R CVD Drive Shaft by GPM TRX4037SANP  [TRX4037SANP]

TRX4 CVD drive shaft screw pins

This GPM aftermarket screw pin set is a direct-fit RC-scale replacement intended for the front and rear CVD drive shafts on TRX4 platforms. The set contains 4pcs intended to replace worn or lost pins that secure CVD joints, restoring reliable engagement and reducing driveline play during trail crawling or scale runs.

Installation is straightforward: remove the affected CVD joint, inspect mating faces for wear, and swap the old pins for the replacement pcs, verifying correct seating and free rotation of the joint before reassembly. These pins serve a maintenance and repair role rather than a performance upgrade, and they help keep suspension and drivetrain geometry consistent during low-speed crawling and technical trail sections.
