If you're looking to properly level out your truck and give it a slightly lifted stance, but want it to still be able to be a daily driver, you've found the right kit. This CST STL (Stock Torsion Location) Lift Kit offers a 3-6" adjustable lift in the front end and 1" in the rear, (the truck will sit level at 4" front and 1" rear lift) . CST's CSK-C3-18-1 lift kit leaves the torsion bar in the stock location and includes a gusseted high clearance cross-members with a full size differential skid plate, fabricated steel / CNC machined front steering knuckles, differential drop brackets, heavy duty bump stop brackets, extended sway bar end links, brake line drop brackets, all necessary install hardware, and O.E. front shock extensions. All necessary hardware is included. In the rear the kit includes billet 1" lift blocks with bump stop pads and heavy duty 3/4" u-bolts.
No cutting of the front differential is required or welding of any kind. CST's 3-6" lift kit retains the factory front wheel track width and has zero compatibility issues with the GM Stabilitrak system.
