Description:
The Kryptonite Stage 3 Leveling Kit with FOX 2.5 Performance Elite Reservoir Shocks is the ultimate suspension upgrade for 2011-2019 Chevrolet and GMC HD trucks. Designed for owners who demand premium ride quality, increased capability, and superior durability, this package combines Kryptonite’s proven suspension components with FOX’s top-tier Performance Elite shock technology.
At the heart of the system are FOX 2.5 Performance Elite shocks featuring large 2.5-inch hard-anodized aluminum bodies, remote reservoirs, race-developed high-flow pistons, and Dual Speed Compression (DSC) adjusters. This allows drivers to fine-tune suspension performance for daily driving, towing, hauling, or off-road adventures while maintaining exceptional control and comfort. The remote reservoir design increases oil and nitrogen capacity to reduce shock fade and maintain consistent damping under demanding conditions.
Kryptonite Upper Control Arms are engineered to maintain proper suspension geometry on leveled trucks while significantly increasing strength over factory components. Combined with Kryptonite re-indexed torsion keys, the system levels the front of the truck without excessive torsion bar preload while preserving ride quality and suspension travel.
Whether you’re towing a heavy trailer, running larger tires, exploring backroads, or simply looking for the best ride quality available from a leveling kit, the Kryptonite Stage 3 Leveling Kit with FOX 2.5 Performance Elite Shocks delivers unmatched performance, control, and reliability.
