Introducing the ReadyLIFT 69-3495 4.0" SST Lift Kit a revolutionary system designed for 2007-2014 1500-series GM 6-lug 4WD SUV/SUTs. This kit boasts ultra-strong TCT free-floating pivot bushings ensuring self-lubrication and eliminating friction. This system significantly boosts ground clearance and accommodates up to 33" tires on aftermarket wheels (commonly 33x12.50 max). Minimal inner fenderwell trimming may be required for 33x12.50 tires but 22x9.5 with 5.5" backspacing or 17x9 +0 offset on a 285/70R17 require no modifications. The ReadyLIFT 4.0" SST Lift Kit raises your GM 1500 4WD SUV's front by 4.0" thanks to rugged powder-coated steel strut extensions that attach directly to the factory strut without any modifications. It features a DOM tubular Upper Control Arm with OEM-style ball joints eliminating the need for spindle alterations. The CNC-machined 6061-T6 billet Aluminum differential drop brackets offer easy front suspension lift without compromising driveline integrity. These brackets are paired with a powder-coated plate steel skid plate for differential protection. To lift the rear this kit includes 3.0" powder-coated steel coil spring spacers that maintain the factory ride. Long and sturdy rear sway bar end links and bump stop extensions ensure proper rear suspension function. Steel rear shock extensions maintain the factory mounting position for the rear shocks offering great ride quality. The ReadyLIFT 69-3495 4.0" SST Lift Kit is designed to enhance your vehicle's ride and handling while providing the desired height. It comes with a Limited Lifetime Warranty and ReadyGuard PowerTrain Warranty. Please note that this kit is for use with aftermarket wheels and may require a wheel spacer for stock wheels to prevent interference with the control arm during full locked turns. Additionally installation may cause rear axle shift necessitating an adjustable rear track bar or drop bracket. Not compatible with rear airbag suspension or AWD models.
