2001-2010 Duramax Stage 3 Leveling Kit with Fox 2.5 HTO Shocks (KRG-25-01-LVL3-FOXHTO)

The Kryptonite Stage 3 Leveling Kit now pairs the proven Kryptonite front end with Fox 2.5 HTO Performance Series shocks for 2001-2010 GM HD trucks. Re-indexed torsion bar leveling keys raise the front up to 2" without cranking the factory adjusters, while boxed upper control arms correct geometry and improve articulation.

The Fox 2.5 HTO shocks carry Kryptonite-spec valving and Hydraulic Top Out technology, which slows the shaft near full extension to stop harsh top-outs. It is a strong fit for trucks running bigger, heavier tires, on or off the road.
