Energy Suspension black spring cushions are a rear leaf spring bushing set for 1984–1996 Chevy Corvette, supplied as four grommets. Constructed from Hyper-Flex performance polyurethane, they are claimed to last significantly longer than OEM rubber and help the suspension function properly during turns, starts and braking, restoring control and ride height while resisting degradation common to conventional rubber components.
