Prothane 7-803 Leaf Spring Eye Shackle Bushing Kit Polyurethane

The Prothane 7-803 Leaf Spring Eye and Shackle Bushing Kit is a direct-fit polyurethane upgrade designed to replace worn, deteriorated OEM rubber bushings in leaf spring suspension systems. In leaf spring suspensions, significant forces are concentrated at the pivot points and shackle mounting locations — making bushing condition critical to ride quality, handling, and load capacity.

Prothane's premium-grade polyurethane outperforms factory rubber by resisting breakdown from oils, road salt, chemicals, ozone, and other environmental contaminants. Unlike soft OEM rubber bushings that compress and deteriorate over time, these polyurethane bushings maintain their shape and performance characteristics for the life of the vehicle.
