Description This complete delrin bushing kit replaces old worn out factory rubber bushings in the front upper and lower control arms. This should be one of the first upgrades any C4 Corvette owner does to significantly improve handling and suspension response. These delrin bushings eliminate unwanted control arm deflection resulting in precise, consistent suspension geometry during hard cornering. Delrin is a low friction, high-wear resistant material with high-strength and stiffness making it ideal for performance suspension joints.  This bushing kit will provide many years of quiet, trouble free driving even under the most extreme conditions. A must for any autocross or track car.   Select the offset lower bushing kit option to gain additional negative camber.   Includes new stainless washers for upper control arms. Detailed instructions included. 100% made in USA.
