Energy Suspension Hyper‑Flex black master bushing set for 1973–1980 Chevrolet and GMC 4WD trucks with aftermarket front springs replaces rubber components with performance polyurethane. Hyper‑Flex resists oils, coolants and UV exposure, outlasting rubber and improving suspension stability under heavy use. The kit reduces wheel hop, helps maintain caster and camber alignment, and provides a durable upgrade for off‑road, towing, or performance applications where longer life and improved control are desired.
