Shock absorbers can make or break the ride quality and enjoyment in any vehicle, not to mention their impact on ultimate capability and driver confidence. Equally important are the shock mount bushings that locate the shock absorber and allow it to function correctly. SuperPro's polyurethane shock mount bushings offer a lifetime of peak performance without the rapid softening and degradation that plagues rubber bushings. An ideal service item for existing stocks in good working order or as part of a shock absorber upgrade or replacement.
