6" MAX2.1 suspension system with vehicle-specific Falcon 2.1 monotube shocks on all four corners, delivering a better-than-factory ride and up to 37" tire clearance for the 2020-2024 Chevy Silverado and GMC Sierra 2500/3500 HD.
ReadyLIFT's 6" MAX2.1 Suspension System is designed to improve stance, performance, and capability on GM HD trucks.

The torsion bar relocation brackets eliminate traditional torsion bar lowering to preserve ground clearance.
