LIFT KIT | 2011-2018 GM 2500HD | 8-10" STAGE 3

Superior fit, function and finish. Improved ride quality, O.E. steering geometry, O.E. CV angles, O.E. track-width, that’s just a few of the many reasons we are known as the 2500HD guys. You could also say we paved the way for sub-frame style lift kits, twenty years ago and long before the current trend. Fifteen years later, like the 2500HD our lift kits are still evolving and still continue to uphold our reputation! The CSTCSK-C3-16-3 kit includes all front & rear lift components to provide a level stance at 8 inches of lift. *SHOCKS SOLD SEPARATE*

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!
Our Stage 3 8-10" 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 lines & drop brackets, CST laser cut torsion x-member drop brackets & all necessary hardware. This kit will also include two 5” fabricated lift blocks with bumpstop pads, an add-a-leaf kit and zinc-plated u-bolts for 7.5 inches of rear lift! *SHOCKS SOLD SEPARATE*

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. Our 8-10" lift kit retains the factory front wheel track width and has zero issues with the GM Stabilitrak system.

With the superior design and the superior quality you have come to expect from CST, this kit continues to be one of our most popular!
