ReadyLIFT presents the new Big Lift Kit for 2019-2022 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.
