CST builds the best suspension systems available on today's market, and we have yet again stepped up to conquer the massive suspension on the 2011-2015 HD trucks.
We've incorporated our extensive knowledge of off road racing and trophy truck quality engineering to ensure you that your suspension will have increased strength, performance, overall integrity, and perform better than stock. Throughout the initial design and R&D process we made sure to retain the factory OEM suspension geometry and design attributes!
Our standard 6-8" adjustable kit in the front end includes our 1 piece gusseted sub-frame w/ steel full size differential skid plate, fabricated steel / CNC machined front steering knuckles, high strength steering drop center link w/ heim jointed support links to minimize wear of 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 drop brackets, all necessary hardware, and front stock shock extensions.
Steering stabilizer brackets are built into the kit and our stabilizer shock kit can be purchased as an option.
In the rear the kit includes a fabricated 4" lift block with bump stop pad and heavy duty 3/4" zinc-plated u-bolts.
Extended length rear shocks are required, but sold separate*
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.
