We've incorporated our experience in off road racing and 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 3 S.T.L. (Stock Torsion Location) 6-8" adjustable lift kit will include 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 line drop brackets, four 2.0 emulsion shocks, all of the necessary install hardware, and O.E. front shock extensions. This kit also includes our hand built S.T.L. front brackets, allowing you to keep the torsion x-member in the stock location!
Steering stabilizer brackets are built into the kit and our stabilizer shock kit can be purchased as an upgrade option.
The rear kit includes fabricated 4" lift blocks with bump stop pads and heavy duty 3/4" zinc-plated u-bolts.
No cutting of the front differential is required or welding of any kind. Our 6-8" lift kit retains the factory front wheel track width and has zero compatibility issues with the GM Stabilitrak system.
