Level Your GM HD Without Breaking The Bank

If you're tired of staring at that nose-down factory rake every time you walk up to your truck, Kryptonite built this kit to fix it fast and affordably. This Stage 3 leveling package brings the front of your 2011-2019 GM Silverado or Sierra 2500HD or 3500HD up to 2 inches closer to level with the rear, using forged torsion keys that are 25% stronger than the factory units. What sets these keys apart is how they grab the flat of the torsion bar itself, giving you a tighter, sturdier fit than keys that just clamp around the round profile. That extra 1 to 2 inches of clearance is enough to fit up to 33 inch tires without the added cost and complexity of a full lift kit. This particular package steps up to Fox 2.5" Performance Series shocks featuring Fox's Hydraulic Top Out technology, which smooths out harsh top-outs and adds real rebound control once you're running heavier, more aggressive tires. Kryptonite also includes upgraded upper control arms, bolt-on upper ball joints, and all the hardware needed, so your suspension geometry and damping are dialed in together rather than left mismatched. For a leveled stance with genuinely upgraded shock technology, this kit delivers real capability at a fraction of a traditional lift kit's cost.

Forged Key Engineering Paired With Fox HTO Shock Technology

The Kryptonite KR11STAGE3FOXHTO is a complete leveling system engineered specifically for 2011-2019 GM Silverado and Sierra 2500HD and 3500HD trucks equipped with the LML or L5P Duramax. This package is designed to provide a maximum of 2 inches of front lift, and Kryptonite is explicit that adjusting beyond that 2 inch limit will most likely result in complete front shock failure, making it critical to stay within the kit's intended range. The forged torsion keys are engineered to grab the flat of the torsion bar for a tighter fit than standard replacement keys, and forging makes them 25% stronger than the factory units. Fox's Hydraulic Top Out technology provides usable, position-sensitive rebound damping control both on and off pavement, forcing shock oil through a secondary shim stack to slow shock shaft speed during rebound, which is particularly beneficial once heavier, more aggressive tires are added or the truck sits higher than OEM specification. The kit includes a pair of Kryptonite upper control arms, 4 control arm sleeves, 8 control arm bushings, 2 bolt-on upper ball joints, a complete hardware package, and 2 leveling keys. Damping is handled by 2 Fox 2.5" Performance Series front shocks (part number KRS4010) and 2 Fox 2.5" Performance Series rear shocks (part number KRS4009).
