YD-2 Rear Upper Pivot Pin for YD-2/PLUS/EX - Yokomo Y2-RAC5  [Y2-RAC5]

Y2-RAC5 rear upper pivot pin overview

The Y2-RAC5 is designed as a direct replacement for the upper arm pivot pin used in the rear suspension of Yokomo YD-2 series cars. It secures the upper arm pivot within the Y2-RAC rear A-arm SP kit and is suited to refresh worn hardware during rebuilds or scheduled upkeep.

Fitting is straightforward: remove the existing pin from the A-arm mount, position the replacement pin through the arm and bracket, and confirm it sits correctly while allowing free articulation. After installation, inspect for sideways play and ensure the suspension cycles smoothly to preserve handling consistency.

From a maintenance perspective, renewing the upper pin is a low-effort way to reduce looseness at the pivot and maintain steady toe and camber under load, helping preserve traction and predictable rear-end behavior on YD-2 chassis.
