Description:
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 make sure to retain the factory O.E. suspension geometry and design attributes!
Our standard 6-8″ adjustable 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 line drop brackets, CST laser cut torsion x-member drop brackets, all necessary hardware, and O.E. front shock extensions.
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.
Extended length rear shocks are required, but sold separate*
No cutting of the front differential required; no welding required. The CST 6-8″ lift kit retains the factory front wheel track width and has zero compatibility issues with the GM Stabilitrak system.
