• Significantly outlasts factory rubber bushings

Why Choose Polyurethane?

Polyurethane bushings offer approximately three times the durability of OEM rubber bushings. They resist shape deformation under load, maintain tighter suspension geometry, and provide superior resistance to automotive fluids and harsh weather conditions. This translates to improved handling, reduced body roll, and fewer suspension-related repairs over the vehicle's lifespan.

Application:

This bushing set is designed for rear leaf spring and shackle applications, providing a direct replacement for factory rubber bushings that have worn, cracked, or deteriorated due to age and use.
