The Kryptonite KR11STAGE3FOXPE Stage 3 Leveling Kit is designed for 2011–2019 GMC Sierra 2500HD/3500HD trucks, providing up to 2 inches of front lift to reduce factory rake and increase tire clearance. This premium system combines Kryptonite upper control arms, re-indexed torsion bar keys, and FOX 2.5 Performance Elite reservoir shocks for improved suspension geometry, ride control, and durability.
FOX 2.5 Performance Elite shocks feature external reservoirs, large aluminum bodies, and Dual Speed Compression (DSC) adjusters for independent high- and low-speed compression tuning. This allows the suspension to be adjusted for highway comfort, towing, heavy loads, or more aggressive off-road use while providing excellent heat management and consistent damping performance.
Heavy-duty Kryptonite boxed upper control arms help maintain proper geometry and alignment at the increased ride height, while re-indexed torsion bar keys provide lift without excessive preload. The system installs without cutting or welding and supports up to 34-inch tires on many applications, depending on wheel and tire configuration.
