Elevate Your Truck's Game with Unmatched Style and Capability

Transform your 2020-2025 GM Chevy Silverado or GMC Sierra 2500/3500 HD with the ReadyLift 3-Inch SST2.1 Lift Kit. Engineered to deliver an aggressive yet refined stance, this premium lift kit makes room for up to 35†tires, giving your truck a bold new look and unparalleled off-road capability.

Built Tough for Performance That Lasts

The SST2.1 Lift Kit features a 3†front lift achieved with forged torsion keys and heavy-duty 4130 chromoly steel upper control arms. These arms come equipped with high-angle ball joints and maintenance-free TCT bushings, ensuring long-lasting durability and optimal suspension geometry. The rear lift blocks maintain a level stance while allowing for increased ground clearance. Falcon 2.1 monotube dampers provide vehicle-specific performance tuning for improved roll control, enhanced low-speed damping, and optimized suspension travel. With durable 6061-T6 aluminum alloy shock bodies, hardened chrome-plated shafts, and precision engineering, this lift kit ensures a smoother ride and exceptional handling on any terrain.

Vehicle Fitment: 2020, 2021, 2022, 2023, 2024, 2025 GM 6.6L Duramax

Notes:

  • When setting the torsion key adjustment bolt do not exceed 27†from the wheel center to the fender edge. Exceeding this will overlift the vehicle creating a top-off condition, meaning the suspension has little to no down travel. The result is poor ride quality and premature wear of components.
