2020-2025 Duramax Stage 2 Leveling Kit (KR20STAGE2)

Note: Will NOT fit on AT4X & ZR2 trucks equipped with DSSV shocks. 

The Kryptonite Stage 2 leveling kits are the easiest, safest, least expensive way to bring the front of your truck 2" closer to the rear. The forged torsion keys are fully adjustable, designed to grab the “FLAT” of the torsion bar for a tighter, sturdier fit, effectively increasing strength by 25% over OEM. Designed to keep the factory ride quality, increase articulation, maintain geometry and will never add pressure on other suspension components.
