Using boxed CST x-members, combined with hand built lift spindle uprights this kit drops the lower arms a full 8 inches to provide a true 8 lift! Our unique spindle design and front differential drop provide superior tie-rod and CV angles while retaining an optimal turning radius! Instead of adding spacers to the top of the O.E. coil-over like most other 6 or larger kits CST provides lower brackets to lift the coil-over up, reducing bump-steer and improving overall handling! This new kit also includes heavy-duty outer tie-rods and an extremely durable aluminum skid plate to protect the bottom of the differential, billet aluminum CV spacers and new sway-bar end links! The rear lift consists of off-set 5 lift blocks, add-a-leafs & new zinc-plated u-bolts with hardware providing 7 inches of rear lift. This system will not cause your Stabillitrak to malfunction. If you're worried about ride quality, don't be. Your truck will maintain its ride quality after being lifted with this kit. You'll also be able to fit up to a 35" wheels 8"-10" wide wheels with 5" of backspace. 37" wheels can be fit with some trimming and removal of rear mud guards.
