ReadyLIFT 8" lift kit for the 2019-2021 Silverado/Sierra 1500 RWD features boxed steel front/rear cross members and full width front skid plate constructed of thick 3/16" plate steel. New 1/4-inch boxed plate steel differential drop brackets feature a double gusset and boxed center rib to take the abuse of front differential torsional twisting.

Their new "clam-shell" style lower strut extension retains use of the factory struts and does not require strut rotation. These new clam-shell brackets utilizes their TCT lower bushings to provide a precise pivot point that maintains the factory ride. The addition of their proprietary new tubular upper control arms with TCT pivot bushings ensures prolonged upper control arm strength which is far superior to the OE stamped steel control arms. To lift the rear, new 5" tall fabricated steel rear blocks with integrated bump stop landings and an add-a-leaf has been added as well as new Bilstein 5100 series rear shocks.

With over nine months of engineering and development and more awesome features than we could possibly mention, the bottom line is this new Big Lift Kit is the best 8" lift kit you can install on a new body style 2019-2021 GM 1500 4WD truck! Thousands of miles of road and trail testing have proven their new 8" lift kit makes these new GM 1500 trucks ride better than stock!
