2020-2026 Duramax HD Stage 2 Leveling System (AXGM20STAGE2)

The Stage 2 Leveling System is a complete front suspension package for 2020-2026 Duramax HD trucks, not just a set of keys. Forged torsion leveling keys provide up to 2" of front ride height to kill the factory rake and clear larger tires, while included shock spacers and extensions restore shock travel so ride quality doesn't suffer. The heavy duty upper control arms use true double-shear construction, identical 3/16" laser cut steel plates hand welded into a rigid boxed structure, and each arm carries an AX6292 Grade 12.9 bolt-on upper ball joint, one of the strongest available for the GM HD platform.
