The Skyjacker C140AKS is a complete 4-inch suspension lift kit engineered for 1973–1987 GM half-ton 4WD trucks. Designed with Skyjacker's signature Softride leaf spring technology, this kit delivers a confident, comfortable ride whether you're tackling rugged off-road terrain or cruising on the highway. Everything needed for a full front and rear suspension lift is included in a single kit.

Kit Includes:

• Front lift leaf springs
• Rear lift leaf springs with rear spring pack
• Front and rear U-bolt kits
• Complete bushing kit
• Detailed installation instructions

Softride Spring Technology:

• Springs are manufactured using American-made high-quality steel
• Individual leaves are shot-peened with hard steel pellets to compress the surface and increase tensile strength
• Shot-peening process maximizes wheel travel and ride quality without sacrificing spring longevity
• Bolt-style spring clips eliminate the friction and binding caused by traditional c-style clip designs
• Tapered leaf design runs over the full length of each spring, distributing load more evenly and reducing leaf-to-leaf digging

The Skyjacker C140AKS suspension lift kit provides the clearance and stance needed for larger tires and off-road use, while preserving ride comfort and handling balance. Backed by Skyjacker's decades of suspension engineering experience, this kit is a trusted upgrade for classic GM 4WD platform trucks.
