LIFT KIT | 2011-2016 GM 2500HD Diesel | 10" STAGE 2

Superior fit, function and finish. Improved ride quality, O.E. steering geometry and O.E. track-width, just a few of the many reasons we are known as the reliable 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 OPCSK-C3-16-9 kit includes front & rear lift components for a level stance at 9-10 inches of lift and four of our Dirt-Series 2.0 reservoir shocks!

Our Stage 2 10" kit for the 2011-16 2500HD includes our 8-10" 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 and all of the necessary hardware. This 10” version of our 8-10” kit also includes a new front drive-shaft, uni-ball upper arms and torsion keys! This kit will also include four of our Dirt-Series 2.0 reservoir shocks along with our soft-ride rear leaf springs, 3” fabricated rear lift blocks with bumpstop pads and zinc-plated u-bolts for 9.5 inches of rear lift!

Steering stabilizer brackets are built into the kit and our stabilizer shock kit can be purchased as an upgrade option.

Cutting or modifying the front differential is not required. Our 8-10" lift kit retains the factory front wheel track width and has zero issues with the GM Stabilitrak system.
