The ReadyLIFT 69-3485 4.0" SST Lift Kit is a complete suspension lift system engineered to raise ground clearance, retain factory ride quality, and support larger aftermarket tires. It combines rugged hardware, CNC-machined components, and bolt-on installation features that avoid irreversible modifications to the factory struts.
*Installation and compatibility notes: Not compatible with AWD Denali trucks; does not work with 2013 Z71 4WD trucks equipped with Rancho front struts. For 2007–2011 Z71 models measure the vehicle prior to purchase—there must be a 2.25" to 2.5" difference between front and rear. Kit is designed for use with aftermarket wheels having approximately 5.25" backspacing; running OE factory wheels with larger tires may require wheel spacers. Not designed for off-road use.
