2020-2025 GM HD 8" Lift Kit w/ Falcon 1.1 Shocks (44-30820)

The ReadyLIFT 8-inch Lift Kit for 2020-2025 GM HD trucks is a comprehensive suspension system designed for owners who want a commanding stance and the ability to run up to 38-inch tires. Engineered with laser-cut heavy-duty steel crossmembers and OE-style cast iron knuckles, this kit ensures perfect suspension geometry and alignment. By integrating fabricated steel upper control arms and vehicle-specific Falcon 1.1 shocks, this system delivers a "better-than-factory" ride quality with increased suspension travel and superior off-road capability.

Features

• Delivers a full 8-inch front lift and a leveled rear stance.
• Includes four (4) Falcon 1.1 Monotube Shocks tuned specifically for GM HD stability and comfort.
• Torsion bar relocation brackets keep torsion bars in their factory location to maximize ground clearance.
• Fabricated steel Upper Control Arms (UCAs) feature corrected ball joint angles for improved durability.
• OE-style cast iron knuckles are precisely engineered to provide ideal steering geometry.
• Includes a heavy-duty steel skid plate and differential drop brackets for essential underbody protection.
• CNC-machined billet aluminum CV axle spacers maintain proper driveline angles for 4WD use.
• Comes with 12-inch sway bar end links and bump stop extensions to ensure full range of motion.

Notes

• Some trucks equipped with a factory Tow Package may require custom-length U-bolts (sold separately) if the standard kit U-bolts are too short.
• Vehicle alignment, headlamp aim, and Advanced Driver Assistance Systems (ADAS) should be recalibrated following installation.
• ReadyLIFT recommends professional installation due to the complexity of the 8-inch suspension overhaul.
