Polyurethane is a recognized performance product and it has a far greater (typically three times) durability than OEM rubber parts. We offer a lifetime warranty on our bushings (excluding spring bushes). Suspension bushes are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and in the most arduous of conditions with no maintenance or lubrication. Our polyurethane bushes will last longer, standing up to road debris, chemicals, oils, compression, and load. The design of our bushings make them much easier and quicker to install than the OEM rubber parts.
