Product Details
The ReadyLift 6" Lift Kit w/Falcon 1.1 Monotube Shocks is made for the 2019-2024 GMC Sierra 1500, giving it more ground clearance and room for larger tires.
The ReadyLIFT 6" Big Lift Kit for 2019-2023 Chevy Silverado and GMC Sierra 1500 trucks features Falcon 1.1 Monotube Shocks for improved ride quality and handling, excluding Trail Boss, ZR2, or AT4/AT4X models. The kit, 44-39605, boasts boxed steel front/rear cross members and a 3/16" plate steel skid plate. It includes 1/4-inch steel differential drop brackets with double gusset and center rib for differential torsional resistance.
The kit's top mount strut extensions are angled and offset, aligning struts for optimal shock performance and reduced wear, while a lower mount strut pre-load spacer slightly increases spring rate for larger wheels and tires. The rear is lifted with 5" fabricated steel blocks with bump stop landings and Falcon 1.1 Monotube rear shocks. Tested for over 9 months, it offers superior ride quality over stock.
