The Probearing SilentSpin bushings offer superior performance compared to polyurethane and OE elastomer bushings. They combine the best features of each: a free-spinning inner sleeve, typical of poly bushings, with the maintenance-free and greaseless advantages of OE elastomer bushings. The SilentSpin bushings are engineered with a composite liner centrally bonded within polyurethane and all securely encased within a steel housing. The inner sleeve is fitted with serrated washers at both ends, creating an ideal interface for bushing rotation, and providing substantial surface area for chassis attachment.
