With the foam material of the original mounts literally turning to dust with age, these guide bushings are often the cause of front-end knocking which can, at times, be misdiagnosed as an expensive front damper or top mount replacement. Our replacement bushings are made from our Yellow 70A durometer polyurethane material for increased performance and durability, providing a cost-effective, fit-and-forget solution that's a worthwhile upgrade as part of any front suspension overhaul.
