Engineered For Strength Ride Quality And Proper Geometry

The ReadyLift 44-30821 8'' Lift Kit is a complete front and rear suspension solution designed for 2020–2025 GM 2500HD and 3500HD 4WD trucks, including AT4 models. It features laser-cut, CNC-formed crossmembers, OE-style cast iron knuckles, and forged torsion keys to deliver the right lift height while preserving alignment geometry and drivability. Included torsion bar relocation brackets keep the bars in their factory location, improving ground clearance and reducing stress on suspension components. The Falcon 2.1 monotube shocks are tuned to manage the increased height and mass, helping maintain control and ride comfort on and off the road. Differential drop brackets and CNC-machined CV axle spacers are included to protect driveline angles, while extended sway bar end links and bump stop extensions help keep the suspension operating within proper limits. The kit also includes a heavy-duty skid plate and OE-style rear lift blocks with integrated bump stop pads. This system is built to handle the weight, power, and real-world demands of GM’s HD trucks without cutting corners on ride or reliability
