Yokomo SD-010RW SDW R. Universal Drive Shaft  [SD-010RW]

Aluminum universal drive shaft for MR-4TC SD WCSP

This is an aluminium universal drive shaft assembly designed specifically for MR-4TC SD WCSP chassis as an RC-scale accessory. The set centres on durable aluminium components where the dogbone, axle and cross spider are all metal rather than plastic, intended to reduce play in the driveline and provide a consistent mechanical interface between gearbox output and wheels.

Installation notes: verify fitment on MR-4TC SD WCSP hubs and gearbox outputs before full assembly, check spline engagement and endplay, and torque fasteners to the values specified in your chassis manual. Because the parts are metal, confirm there is no binding after installation and recheck wheel alignment and drivetrain rotation at low speed.

Tuning role: replacing stock plastic driveline parts with aluminium items like this changes the feel of the drivetrain by reducing flex and slop, which can improve throttle response and consistency in corner exit when used on precision touring setups; expect a different wear pattern and monitor mating parts such as bearings and pins for signs of increased load.
