The Skyjacker Add-A-Leaf for 1999–2006 GMC Sierra 1500 4WD is a rear auxiliary leaf that provides lift and added load support by inserting into the factory leaf spring. Softride add-a-leafs use American steel and are shot-peened at high velocity to increase tensile strength; they are typically pre-drilled for the center pin and feature tapered ends for a progressive feel. Constructed as multileaf packs with load capacity equal or greater than OE and a limited lifetime warranty.
