The Superlift front leaf spring for 1973–1987 GM heavy-duty pickups is specified for use with an 8-inch lift kit to achieve significant front ride height. Sold individually, it’s intended to preserve axle geometry and carrying capacity within large-lift builds. Superlift’s long history designing truck suspension components informs the spring’s role in balancing lift with practical drivability.
