4.0-in Suspension System with single front shocks. The Ford Super Duty truck is an awesome performer in stock trim. The addition of a Full-Traction Suspension System makes it better. The 4-in lift system is designed to not only provide lift, but to improve ride quality and retain what is most important: Payload.

Multi-leaf front springs are computer designed to provide maximum travel and deflection, and maintain durability over the long haul. Precision, laser cut components, and top quality hardware throughout this system means excellent fit, and long service life for your rig's suspension system.

Kit comes standard with front leaf springs, rear add-a-leaf and blocks, track bar relocation bracket, drop pitman arm, sway bar extensions, urethane bump stops, and 4 shocks with boots (optional).
