OVERVIEW

The Cusco Rear Upper Control Arm Pillowball Bushing Set upgrades the soft, high-deflection factory rubber bushings located on the outer knuckle side of the rear suspension setup. Utilizing premium, high-precision spherical bearings, this set locks down the connection point between the rear upper arm and the knuckle assembly. By stopping unwanted twisting and lateral deflection under load, this kit keeps your rear wheel alignment perfectly stable during aggressive track driving, cornering acceleration, and heavy braking transitions.
