ReadyLIFT® now offers all-new Big Lift Kit for the new 2019-2022 MY Chevy Silverado and GMC Sierra 1500 trucks! Introducing the ReadyLIFT 8" Big Lift Kit engineered for incredible ride quality and superior handling performance.

44-3980 - 8"F-6.5"R Big Lift Kit - GM Silverado/Sierra 1500 4WD

Note: Not for use on Trail Boss, AT4, AT4X, ZR2 or Denali models.

Note:  Not compatible with Adaptive Ride Control or Multimatic™ suspension.

The 44-3980 lift kit utilizes the very best in ReadyLIFT engineering with 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.

Our 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 our TCT lower bushings to provide a precise pivot point that maintains the factory ride. The addition of our 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 2019-2022 GM 1500 4WD truck! Thousands of miles of road and trail testing have proven our new 8" lift kit makes these new GM 1500 trucks ride better than stock!
