This Energy Suspension rear leaf spring and shackle bushing set fits 1973–1979 Ford F-100/F-150 2WD applications and is molded from Hyper-Flex polyurethane. The upgraded bushings are engineered to outlast conventional rubber by roughly five to ten times, improving suspension durability and helping the vehicle remain more controlled during turns, acceleration, braking and over bumps.
