Built for the ReadyLift 44-39805 Big Lift Kit for 2019-2023 Chevy Silverado & GMC Sierra 1500 4WD, this ReadyLIFT component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.

ReadyLIFT presents the new Big Lift Kit for 2019-2023 Chevy Silverado and GMC Sierra 1500 trucks, the 44-39805 - 8"F-6.5" R Big Lift Kit, designed exclusively for 4WD models. This kit is not suitable for Trail Boss, AT4, AT4X, ZR2, or Denali models, nor is it compatible with Adaptive Ride Control or Multimatic suspension. Additionally, it cannot be used with vehicles that have rear composite mono-leaf springs, identifiable by round U-bolts; it only fits traditional steel leaf springs with square U-bolts. The kit features boxed steel front/rear cross members and a 3/16" plate steel skid plate. Its 1/4-inch steel differential drop brackets are double gusseted with a boxed center rib for durability. The lower strut extension retains factory struts without needing rotation, using TCT lower bushings for a precise pivot point. New tubular upper control arms with TCT pivot bushings replace the OE stamped steel control arms for enhanced strength. The rear lift includes 5" tall fabricated steel blocks with integrated bump stop landings and an add-a-leaf, alongside Falcon 1.1 Monotube rear shocks. Extensively tested, this 8" lift kit significantly improves ride quality over stock. It allows for up to 37x12.50 tires on 20x9 0 offset wheels without trimming; 20x10 -18 offset wheels will require minor trimming of the front valance, felt liner edges, and mud flaps. The use of Auto 4 Hi feature is not recommended. The kit maintains the factory ride and handling, includes tube steel upper control arms with maintenance-free pivot bushings and 1-ton ball joints, and comes with ReadyGuard Powertrain Warranty.

The ReadyLift 44-39805 Big Lift Kit is designed to enhance the off-road capability and aggressive stance of your 2019-2023 Chevy Silverado and GMC Sierra 1500 4WD trucks. Crafted with precision, this kit features boxed steel cross members and a durable 3/16-inch plate steel skid plate, providing robust protection for your vehicle's undercarriage during rugged adventures. The kit includes fabricated steel blocks with bump stop landings and an add-a-leaf for a 5-inch rear lift, complemented by Falcon 1.1 monotube shocks that deliver improved damping and ride quality.
The front lift components consist of an 8-inch spacer combined with tubular upper control arms equipped with maintenance-free pivot bushings and 1-ton ball joints, replacing OE stamped steel arms for increased strength and durability. The lower strut extensions retain factory shocks without rotation, ensuring proper alignment and handling. This lift kit is specifically designed for 4WD models with traditional steel leaf springs, excluding models with rear composite mono-leaf springs or specific factory features like Adaptive Ride Control.
Installation requires professional expertise and approximately five hours, offering a straightforward upgrade for experienced enthusiasts. Once installed, the kit allows for up to 37-inch tires on 20x9 wheels with zero offset, and minor trimming may be necessary for 20x10 wheels with -18 offset. The ride maintains factory handling characteristics, providing a balance of off-road performance and everyday drivability. The kit also includes Falcon 1.1 shocks for the rear and comes with ReadyGuard Powertrain Warranty, ensuring peace of mind. This product complies with California Proposition 65 regulations, warning about potential chemical exposure during manufacturing. Suitable for a range of Silverado and Sierra models from 2019 to 2022, this lift kit is an excellent choice for those seeking increased ground clearance and a commanding presence on and off the road.
