Part # KR20STAGE3FOX
The Kryptonite Stage 3 Leveling Kit for 2020–2026 GM HD trucks is the ultimate bolt-on solution for leveling and improving your truck’s ride and handling. Whether you're towing, daily driving, or adventuring off-road, this system is built for maximum reliability and performance.
Included forged torsion keys allow for precise front lift adjustment (1”–2”) without sacrificing ride quality. To handle the extra height and preserve proper suspension geometry, the kit includes Kryptonite’s boxed upper control arms with bolt-in ball joints—designed for strength and serviceability.
The Fox 2.0 Performance Series shocks are tuned specifically for GM HD trucks and provide fade-free, race-proven control on and off the pavement. With this setup, you'll gain clearance for up to 34” tires, while preserving your truck’s factory comfort and drivability.
