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

Replacement upper A-arm pin for Yokomo YD-2 rear

The Y2-RAC5 pin is a direct-fit replacement for the upper A-arm position used on Yokomo YD-2 series rear suspension assemblies. It acts as the retention pin that secures the upper arm pivot in the Y2-RAC rear A-arm SP kit and is ideal when worn pins are replaced during routine service.

Installation is simple: remove the old pin from the A-arm mount, align the replacement pin with the arm and suspension bracket, then seat it so the arm articulates freely. After fitting, check for any lateral play and confirm smooth movement through the full suspension travel to preserve predictable handling.

Although small, this part helps maintain rear geometry by reducing play at the upper pivot, which supports consistent toe and camber under load. Replacing worn pins is an efficient way to restore crisper steering response and more consistent rear traction on YD-2 platforms.
