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, 2012, 2013, 2014 & 2015 HD trucks.
We've incorporated our extensive knowledge of off road and trophy truck quality technology and can insure 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, and not change it like some of the other guys.
This 6-8" adjustable kit 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 of the necessary hardware and four 2.0 DIRT-SERIES re-buildable emulsion shocks.
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" 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.
