2020-2026 Duramax HD Stage 3 FOX 2.5 Performance Elite Leveling System (AXGM20STAGE3FOX2.5ELITE)

This is the top of Axiom Supply's GM HD lineup: a complete Stage 3 leveling package built around FOX Performance Elite Series 2.5 Reservoir shocks at all four corners. Forged torsion leveling keys add up to 2" of front ride height, double-shear upper control arms correct the geometry, and the remote-reservoir FOX 2.5s keep damping consistent through heavy towing and long off-road runs. Everything bolts on with no compromises for a 2020-2026 Silverado or Sierra HD.
