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

The Stage 3 FOX 2.5 system pairs Axiom Supply's leveling and geometry correction hardware with a full set of FOX 2.5 Performance Series HTO shocks tuned for leveled GM HD trucks. Forged torsion keys add up to 2" of front ride height, double-shear upper control arms restore proper suspension angles, and the large-bore HTO shocks use position-sensitive rebound control to eliminate harsh top-out on bigger tires. One complete bolt-on package for a 2020-2026 Silverado or Sierra HD.
