Kryptonite leveling kits are the fastest, safest, least expensive way to bring the front of your GM Truck 2 inches closer to the rear. Our torsion keys are designed to grab the torsion bar's flat for a tighter, sturdier fit. Kryptonite torsion keys are forged, making them 25% stronger than the factory and primed to last the life of your vehicle. The adjustable torsion key provides 1-2 inches of lift and gives clearance to add up to 34" wheels and tires to your GM Truck. Designed to keep the factory ride and will not add more pressure on the stock suspension components. Through our innovative engineering, these kits cost thousands less than a traditional lift kit.
