Introducing ReadyLIFT's innovative 8" Big Lift Kit designed specifically for the 2019-2021 MY Chevy Silverado and GMC Sierra 1500 trucks. This kit is engineered to provide exceptional ride quality and superior handling performance. Please note that it is not compatible with Trail Boss, AT4, AT4X, ZR2, or Denali models, as well as vehicles equipped with Adaptive Ride Control or Multimatic ¾ suspension or rear composite mono-leaf springs. The kit includes boxed steel front/rear cross members, a full-width front skid plate made of thick 3/16" plate steel, and 1/4-inch boxed plate steel differential drop brackets with double gussets and boxed center ribs to handle front differential torsional twisting. The lower strut extension, in a unique "clam-shell" style, retains the factory struts without requiring rotation and maintains the factory ride with TCT lower bushings. The kit also features proprietary tubular upper control arms with TCT pivot bushings for increased strength compared to OE stamped steel control arms. To lift the rear, fabricated steel rear blocks, an add-a-leaf, and Falcon 1.1 Monotube rear shocks are included. After nine months of rigorous engineering and testing, this Big Lift Kit proves to enhance the ride quality of these GM 1500 trucks significantly. It accommodates up to 37x12.50 tires on 8-inch kits with 9" wide wheels and 0 offset, with minor trimming required for -18 offset. The kit maintains factory ride and handling, offers increased tire size clearance, features maintenance-free pivot bushings, heavy-duty steel components, and includes the ReadyGuard Powertrain Warranty, making it the ultimate choice for lifting your 2019-2021 GM 1500 4WD truck.
