Built for the ReadyLift 6-Inch Big Lift Kit for Chevy Silverado and GMC Sierra 1500 (Part #44-39605), this ReadyLift component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.

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.

The ReadyLift 6-inch Big Lift Kit, part number 44-39605, is designed specifically for 2019-2023 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks to enhance off-road capability and aesthetic appeal. This kit features premium Falcon 1.1 Monotube shocks that deliver improved ride quality and handling, providing a smoother driving experience over stock suspension systems. It is compatible with models excluding Trail Boss, ZR2, and AT4/AT4X variants, and is intended for trucks with traditional steel leaf springs, not compatible with adaptive or multi-matic suspension systems.
The kit includes robust boxed steel front and rear cross members along with a 3/16-inch plate steel skid plate, ensuring durability and protection for the vehicle’s undercarriage. Differential drop brackets with double gusset reinforcement and a center rib are incorporated to resist torsional forces and maintain proper alignment, contributing to vehicle stability during aggressive driving. The top mount strut extensions are specially angled and offset to optimize shock performance, reduce wear, and preserve factory geometry, while a lower mount pre-load spacer increases spring rate for accommodating larger wheels and tires.
Rear lift is achieved with 5-inch fabricated steel blocks featuring bump stop landings, paired with Falcon 1.1 monotube shocks for consistent damping and ride quality. The maximum tire size supported by this lift kit is 35 inches, with options for different wheel offsets and minor trimming required for certain configurations. Trimming includes adjustments to the front valance, felt liner edges, and mud flaps to ensure clearance and proper fitment. Installation is complex and generally requires professional expertise, with an estimated time of over 5 hours.
Designed to maintain factory ride quality and handling characteristics, this lift kit allows for increased ground clearance and off-road capability without sacrificing on-road comfort. It includes all necessary components, shocks, and a ReadyGuard Powertrain Warranty for peace of mind.
