The Yokomo Z2-009R3A rear suspension arm pin is a direct-fit replacement for YZ-2DTM3 and CAL3 platforms, made to restore precise pivot alignment and extend service life. It helps keep the rear suspension tracking correctly during high-load conditions.
Using a 3mm pin at the outer rear arm ends ensures the arms rotate on a firm axis, improving cornering consistency and limiting slop that can upset handling at speed.
