The Skyjacker Add-A-Leaf for 2005–2017 Ford F-250 Super Duty is a rear auxiliary leaf that increases ride height by about 1–1.5 inches while strengthening the rear spring and improving load support. Softride add-a-leafs use American steel and are shot-peened to enhance tensile strength; they are typically pre-drilled for the center pin and designed for progressive ride comfort. Constructed as multileaf packs with load capacity equal or greater than OE and a limited lifetime warranty.
