Description

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. Maximum recommended tire size is 20x9 0 offset with 35x12.50 tire without trimming, and 20x10 -18 offset with 35x12.50 or 325/60R20 with trimming. Trimming includes front valance, felt liner edges, and mud flap. Not suitable for Auto 4 Hi, Adaptive Ride Control, Multimatic vehicles, or trucks with composite mono-leaf springs. Compatible only with traditional steel leaf springs. Features include maintained factory ride and handling, clearance for up to 35'' tires on 6-inch kits, factory geometry retention with top mount strut extensions, 3/16-inch steel plate cross members and skid plate, anti-torsion differential drop brackets, and fabricated steel rear lift blocks. Includes Falcon rear shocks and ReadyGuard Powertrain Warranty.

Tyler and his team have done a couple different jobs for me this year on two different trucks. The quality of work was outstanding.
