ReadyLIFT: 6” and 8” Big Lift Kits for ’19-’20 GM 1500 4WD

After an extensive period of development, ReadyLIFT has announced 6” and 8” Big Lift Kits for 2019–2020 Chevy Silverado 1500 4WD and GMC Sierra 1500 4WD pickups (not for Trail Boss or AT4 models). Allowing for the use of 35” and 37” tires, respectively, these new kits are engineered to provide outstanding ride quality and superior handling.

Both the 6” (PN 44-3960) and 8” (PN 44-3980) kits realign struts to optimize shock performance and minimize wear. The specially designed lower mount strut preload spacer slightly increases the spring rate to better handle larger wheels and tires (which are a big reason you want these kits in the first place!). They also include new fabricated steel rear blocks with integrated bump stop landings and Bilstein 5100 Series rear shocks.

The 8” kit additionally features ReadyLIFT’s proprietary “clam shell” style lower strut extensions (eliminating the need for strut rotation or flipping), DOM-steel upper controls arms for perfect alignment geometry at that height, and an add-a-leaf rear spring for a 3/4” rake.
