Replacement Upper A-arm Pin Set for YD-2/PLUS/EX - Yokomo Y2-RAC5  [Y2-RAC5]

Rear upper arm pin: fit and function

The Y2-RAC5 upper A-arm pin is supplied as a direct replacement for the upper pivot used on Yokomo YD-2 rear suspension assemblies. It secures the upper arm pivot in the Y2-RAC rear A-arm SP kit and is suitable for replacing worn pins during maintenance or rebuilds.

To fit the pin, remove the old pin from the A-arm mount, align the new pin with the arm and bracket, and seat it while confirming the arm moves freely. After fitting, inspect for any lateral movement and ensure the suspension operates smoothly through its travel to retain predictable handling.

Replacing this component addresses slop at the upper pivot and helps maintain consistent toe and camber when the chassis is loaded, supporting steadier rear traction and more reliable steering response on YD-2 cars.
