Skyjacker 1999-2006 GMC Sierra 1500 4 Wheel Drive Add A Leaf

Softride(R) Add-a-leafs use only American steel and are shot-peened with hard steel pellets at very high velocities. This shot-peening compresses the surface of the steel thereby increasing the tensile strength of the leaf. Without this shot-peening procedure, the maximum wheel travel and ride quality could not be achieved without sacrificing the life of the leaf. The Skyjacker(R) add-a-leafs are pre-drilled for the center pin. Pin location varies with each application. Most have long tapered ends for a progressive affect and ride comfort.Installation InstructionsThis Part Fits: Year Make Model Submodel 1999-2005 Chevrolet Silverado 1500 Base 2016-2017 Chevrolet Silverado 1500 Custom 2014-2017 Chevrolet Silverado 1500 High Country 2004-2006,2009-2013 Chevrolet Silverado 1500 Hybrid 1999-2006,2008-2013,2015-2017 Chevrolet Silverado 1500 LS 1999-2017 Chevrolet Silverado 1500 LT 2007-2017 Chevrolet Silverado 1500 LTZ 2015-2017 Chevrolet Silverado 1500 SSV 2002-2004,2006
