XDP carries the ReadyLift 44-30600 6" Big Lift Kit with Falcon 1.1 Shocks that allows you run 37” tall tires in your 2020-2022 GM 6.6L Duramax 2500/3500 (4WD). This lift kit comes with cast iron OE-style knuckles with the perfect geometry built-in and laser-cut, fabricated heavy-duty steel cross-members. Torsion arm brackets and front torsion bar relocation brackets will retain the stock position of the torsion bars to keep intact. These torsion bar relocation brackets remove the need to lower the torsion bars, which can impede ground clearance from a lift installation and help to enhance the overall driving experience. Each kit comes with differential drop brackets and CV axle spacers that are crucial front suspension geometry. Bump stop extensions, 12” sway bar end links, factory style cast iron rear lift blocks, heavy-duty steel skid plate, and Falcon 1.1 Monotube shocks round out this kit.
