Part # KR20STAGE3FOXHTO
The Kryptonite Stage 3 Leveling Kit featuring Fox 2.5 HTO Performance Series shocks is the ultimate suspension upgrade for 2020–2026 GM HD trucks. Designed for performance, strength, and real-world reliability, this package delivers more than just ride height—it delivers capability.
Kryptonite’s forged torsion keys lift the front end up to 2 inches while maintaining OEM ride characteristics.
