Zone 4" Suspension Lift Kit 19-21 GMC/Chevrolet 1500 4WD

This 4" IFS lift kit takes advantage of the stock suspension design to maintain comfort and handling characteristics, while offering clearance for up to 35" tires. At the heart of this new kit, a pair of 1/4" steel drop crossmembers repositions the stock lower control arms. for additional ground clearance. A differential skid plate reinforces the subframe while adding protection for critical steering and driveline components. A pair of specially designed steering knuckles maintains proper steering geometry and ESC system compatibility, and allows for 17" or larger aftermarket wheels to be installed - as well as the stock 20's. The front differential is secured using a multipoint differential relocation brackets to keep the CV axle operating angles at a minimum. Lift is provided by a set of top-mounted strut spacers that allow for easy installation without the need to disassemble the factory struts. A pair of sway bar drop brackets are used to correct the operating angle of the factory sway bar and to reinforce the rear crossmember and frame. In the rear, a 3" lift block and longer U-bolts lift and level the truck's stance. Rear brake line / ABS line brackets allow the use of factory brake lines.
