2020-2026 Duramax HD Stage 3 FOX 2.0 Performance Leveling System (AXGM20STAGE3FOX2.0)

The Axiom Supply Stage 3 system levels your 2020-2026 GM HD and fixes the geometry problems a basic key kit leaves behind. Forged torsion leveling keys add up to 2" of front ride height, true double-shear upper control arms restore proper operating angles, and a full set of vehicle-specific FOX Performance Series 2.0 IFP shocks (front and rear) handles the damping. It is a complete bolt-on package for trucks that tow, haul, and see rough ground.
