Kryptonite Stage 3+ Leveling Kit with Fox 2.5 Elite Series Shocks
Fits 2020-2024 Duramax 2500/3500 HD Trucks

Kryptonite leveling kits are the fastest, safest, least expensive way to bring the front of your Duramax 2 inches closer to the rear. Our torsion keys are designed to grab the “FLAT” of the torsion bar for a tighter, sturdier fit. Torsion keys are forged, making them 25% stronger than OEM and primed to last the life of your vehicle. The adjustable torsion key provides 1” to 2” of lift and gives clearance to add up to 34" wheels and tires to your GM 3/4 ton. Through our innovative engineering, these kits cost thousands less than a traditional lift kit.
