The Cusco pillowball bushing kit replaces rear sway bar link arm bushings for GRB chassis applications, using a stiff pillowball-style joint at the linkage to reduce deflection. This hardware tightens sway bar response and improves rear anti-roll behavior without altering the bar itself. It’s a targeted upgrade for drivers who want a more direct connection between the sway bar and suspension on GRB models.
