The Superlift rear leaf spring for 1973–1987 GM heavy-duty pickups is designed for use with an 8-inch lift kit to achieve the rear ride height match. Sold individually, the spring supports rear axle placement and load handling in lifted applications. Superlift’s truck-focused development aims to provide rear suspension components that keep lifted rigs stable and roadable while delivering the intended lift.
