Firm polyurethane bushings replace old deteriorated rubber pieces that allow too much "slop" in suspensions. Whether off-roading, drag-racing, canyon carving or just running down the highway, these 1968-1979 Air Cooled VW 6 piece Polyurethane A-Arm Bushings make your car feel more solid and planted, reducing wander and shimmy. Tech Note: Special Polyurethane compound reduces squeaking but we highly recommend the use of our Polyurethane Bushing Grease for added longevity and silent operation.
