The ReadyLIFT 6-Inch Big Lift Kit, designed for 2019-2023 Chevy Silverado and GMC Sierra 1500 4WD trucks, is a comprehensive upgrade excluding Trail Boss, AT4/AT4X models. This kit, model 44-3965, enhances ride quality and handling through advanced engineering.
It includes boxed steel front/rear cross members and a 3/16-Inch thick steel front skid plate. The kit also features 1/4-Inch steel differential drop brackets with double gusset and boxed center rib for torsional strength.
Strut extensions are angled and offset, aligning struts for optimal shock performance and minimal wear, complemented by a lower mount strut pre-load spacer for spring rate improvement. For rear elevation, 5-Inch tall fabricated steel blocks with bump stop landings are paired with Bilstein 5100 series shocks.
Engineered over 9 months with extensive testing, this kit provides superior ride quality, even surpassing the stock setup. It supports maximum tire sizes of 35x12.50 on 20x9 wheels with 0 offset without trimming, and with trimming, accommodates 35x12.50 or 325/60R20 on 20x10 wheels with -18 offset.
Trimming involves the front valance, felt liner edges, and mud flap. Not suitable for Auto 4 Hi, Adaptive Ride Control, Multimatic vehicles, or rear composite mono-leaf springs.
