The Skyjacker CR24S Softride Rear Leaf Spring delivers 4 inches of lift for 1969–1991 Chevrolet and GMC K10, K20, and K30 4WD pickups and Suburbans equipped with 56-inch rear springs. Sold individually — two springs required for a pair. Softride Technology: Skyjacker Softride springs are tapered at the leaf ends to create more flex throughout the spring pack. This tapering distributes loads more evenly over a greater area and reduces the tendency for one leaf to dig into the leaf above it, improving ride quality and longevity over standard leaf springs. Bolt-Style Spring Clips: Softride springs use bolt-style spring clips that eliminate friction. Standard spring designs use cinch-style bend clips that bend tightly over the spring leafs and cause binding — the bolt-style clips used on Softride springs eliminate that friction entirely. Shot-Peened: Skyjacker leaf springs are individually shot-peened with hard steel pellets at very high velocities for increased strength and fatigue resistance. Pre-Installed Rubber Bushings: These leaf springs come with rubber bushings pre-installed.
