We've combined our experience in off road racing with trophy truck quality engineering to ensure that your suspension will have increased strength, performance, overall build integrity and perform better than stock. Throughout the initial design and R&D process we made sure to retain the factory O.E. suspension geometry and design attributes!
The Stage 4 8-10" adjustable lift kit for the front end includes our one-piece gusseted sub-frame with a steel full size differential skid plate, fabricated steel, CNC machined front steering knuckles, high strength steering drop center-link with heim jointed support links to minimize wear of the factory idler and pitman arms, differential drop brackets, heavy duty bump stop brackets, extended sway bar end links, brake lines & drop brackets, CST laser cut torsion x-member drop brackets and all of the necessary hardware. This kit will also include four of our Dirt-Series 2.0 shocks along with 5” fabricated rear lift blocks with bumpstop pads, an add-a-leaf kit and zinc-plated u-bolts for 7.5 inches of rear lift!
Steering stabilizer brackets are built into the kit and our stabilizer shock kit can be purchased as an upgrade option.
No cutting of the front differential is required or welding of any kind. This 8" lift kit retains the factory front wheel track width and has zero compatibility issues with the GM Stabilitrak system.
With our superior design and the superior quality you have come to expect from CST, this kit will continue to be one of our most popular!
