Ultimate GM Leveling Kit Improves Ride Height and Control
If you're looking to level out your 2020–2025 GM HD truck without compromising ride quality or long-term durability, the Kryptonite Stage 4 Leveling Kit with FOX Shocks is the perfect solution. Whether you're trying to eliminate that factory rake, gain some extra clearance for 34-inch tires, or improve your truck's handling on and off-r ad, this kit delivers serious performance in a complete bolt-on package. At the heart of the system is a pair of forged Kryptonite torsion keys. These keys are built to grab the flat of the torsion bar for a tighter, more secure fit than stock, and are rated to be 25% stronger than OEM, so you can count on them to hold up to heavier loads and tough terrain. The adjustable design allows for up to 2 inches of lift up front, enough to level out your stance without overextending the factory geometry or putting extra stress on your suspension components.
Premium Upper Control Arms with Front & Rear FOX Shocks
This Stage 4 kit also includes upgraded upper control arms, engineered with precision and strength in mind. They're paired with Kryptonite’s bolt-on upper ball joints, offering increased travel and articulation to complement the added lift. Everything bolts together using high-quality hardware and bushings, included right in the box. But what really sets this kit apart is the shock upgrade. FOX 2.5 Performance Series shocks, front and rear, deliver a massive improvement in damping control, comfort, and responsiveness. Thanks to FOX's Hydraulic Top Out (HTO) technology, rebound is better managed under extreme extension, reducing harsh top-outs and providing a more planted feel. It's especially helpful if you're running heavier wheels and tires or hauling gear off-pavement. Better yet, installation is straightforward and designed for bolt-on fitment, no cutting or welding required. And with Kryptonite’s legendary lifetime warranty backing every component, you’ll have peace of mind knowing this kit is built to go the distance.
