Level Up Your Ride with Confidence

Take your 6.6L Duramax to the next level with the Kryptonite KR10STAGE3 Stage 3 Leveling Kit, engineered specifically for 2001–2010 GM Silverado/Sierra 2500HD and 3500HD trucks. Whether you're leveling out your stance, upgrading from worn-out suspension components, or prepping for larger tires, this kit provides the perfect balance of ride quality, strength, and reliability.

At the heart of the system are Kryptonite’s laser-cut, boxed upper control arms—designed to withstand serious abuse while maintaining correct suspension geometry. These UCAs improve performance whether you're running stock height, a leveled setup, or a full suspension lift. Each arm is fitted with bolt-on ball joints and high-quality bushings for smooth articulation and long-term durability.

Paired with FOX Performance Series shocks, this kit delivers premium ride comfort and handling both on and off-road. The leveling torsion keys provide up to 2 inches of lift, giving you additional clearance for tires up to 32 inches in diameter.
