The Superlift rear leaf spring for 1969–1987 GM pickups is designed for 5.5-inch lift kit installs to set rear ride height and keep axle alignment. Sold individually, it complements lift systems by supporting load and rear suspension geometry. Superlift’s heritage in truck suspension development guides the spring’s role in balancing clearance and everyday drivability for lifted GM trucks.
