Introducing the ReadyLIFT 4.0" SST Lift Kit for 2007-2013 1500-series Silverado/Sierra 6-lug 4WD Trucks. This kit features ultra-strong TCT free-floating pivot bushings for self-lubrication and friction elimination. This kit accommodates tire sizes up to 33" on aftermarket wheels. Popular tire options include 33x11.50 on 22x9.5 wheels with 5.5" backspacing, 17x9 wheels with a +0 offset on a 285/70R17, or with minor trimming, a 295/70R17. Note that this kit is designed for use with aftermarket wheels. The 4.0" SST Lift Kit raises the front of your 2007-2013 Silverado/Sierra 1500 4WD truck by 4.0" using robust 4.0" powder-coated steel strut extensions that attach directly to the factory strut without any irreversible modifications. Our kit includes a 100% DOM tubular Upper Control Arm with OEM-style ball joints, eliminating the need for spindle modifications. Our CNC-machined 6061-T6 billet Aluminum differential drop brackets ensure perfect front axle and CV angles without compromising driveline integrity, and they come with a sturdy powder-coated plate steel skid plate for differential protection. To lift the rear, this system includes 3.0" OEM-style cast iron rear lift blocks and u-bolts, providing the correct pinion angle correction and axle locating ears for optimal performance. A set of steel rear shock extensions keeps your factory rear shocks in their original position, maintaining excellent ride quality. As with all ReadyLIFT products, the 69-3485 SST Lift Kit System is backed by our Limited Lifetime Warranty. Please note that this kit is compatible with aftermarket wheels with a backspacing of 5.25". If you use stock wheels with larger tires, you'll need our CNC-machined billet Aluminum wheel spacer (10-3485). It's essential to mention that this kit does not work with AWD Denali Trucks or 2013 Z71 4WD trucks with Rancho front struts. For 2007-2011 Z71 trucks, precise measurements are required to ensure compatibility. This kit is not designed for off-road use.
