Description:
The Kryptonite Stage 3 Leveling Kit with FOX 2.0 Performance Series IFP Shocks is engineered specifically for GMT800 GM 1500 trucks that demand superior ride quality, improved handling, and increased front-end durability. By combining Kryptonite’s proven suspension geometry with FOX’s race-proven monotube shock technology, this system delivers a leveled stance with exceptional control both on and off the pavement.
FOX 2.0 Performance Series IFP shocks feature a 2.0-inch impact-extruded aluminum body for excellent heat dissipation and corrosion resistance, while the Internal Floating Piston (IFP) separates the shock oil from the nitrogen charge to eliminate aeration and maintain consistent damping under demanding conditions. The monotube design provides precise suspension control, improved stability, and fade-free performance whether you’re commuting, towing, or exploring rough terrain.
Kryptonite boxed upper control arms correct suspension geometry on leveled applications while providing significantly greater strength and long-term durability than the factory components. The included Kryptonite re-indexed torsion keys level the front of the truck properly without overloading the factory torsion bar adjusters, resulting in improved ride quality and suspension travel compared to simply cranking the stock keys.
Built for GMT800 owners who expect more from their suspension, this complete system delivers the durability, handling, and ride quality needed for daily driving, towing, and off-road use.
