Universal Drive Shaft Upgrade for MR-4TC SD WCSP SD-010RW by Yokomo  [SD-010RW]

Lightweight aluminium dogbone upgrade for MR-4TC SD WCSP

This aluminium universal drive shaft assembly is intended for MR-4TC SD WCSP applications as an aftermarket RC part. The components replace plastic dogbone, axle and cross spider parts with metal, reducing play and delivering a firmer mechanical link between gearbox output and the wheels.

Installation notes: verify that the parts seat correctly on MR-4TC SD WCSP hubs and gearbox outputs prior to final assembly, check spline engagement and axial play, and follow the torque recommendations in your chassis manual. After fitting, confirm there is free rotation without binding and recheck wheel alignment.

Tuning role: installing aluminium driveline components reduces flex and looseness, which can sharpen throttle response and help with consistent corner exits on precision touring cars; monitor mating bearings and pins for increased wear.
