Kryptonite - Stage 3 Leveling Kit with FOX Shocks - 2001–2010 Chevy/GMC HD & 2002–2009 Hummer H2
Part # KR10STAGE3FOX
The Kryptonite Stage 3 Leveling Kit with Fox Shocks is the ultimate front-end upgrade for your GM HD truck or Hummer H2. Whether you're leveling your stance for a larger tire fitment or upgrading your front suspension for better on- and off-road performance, this kit delivers everything in one proven package.
At the heart of the system are Kryptonite's boxed upper control arms, designed to maintain factory geometry while drastically improving strength and serviceability. Paired with Fox Performance Series 2.0 IFP Shocks, this kit improves both comfort and durability—especially on rough roads, work sites, or trails.
The leveling torsion keys provide up to 2” of front lift, offering clearance for up to a 33” tire, while retaining proper ride quality and alignment. Optional Cam Bolt Kit is recommended for enhanced alignment control, particularly in harsh climates or on high-mileage vehicles.
