Product Details
The ReadyLift 8" Lift Kit is made for the 2019-2022 GMC Sierra 1500, giving it more ground clearance and room for larger tires.
This kit, engineered for excellent ride quality and handling, is not suitable for Trail Boss, AT4, AT4X, ZR2, or Denali models, nor is it compatible with Adaptive Ride Control, Multimatic suspension, or vehicles with rear composite mono-leaf springs. It's designed for trucks with traditional steel leaf springs, identified by square U-bolts. The 44-3985 kit features boxed steel front/rear cross members and a 3/16" thick steel front skid plate.
The 1/4-inch steel differential drop brackets are double gusseted and ribbed for strength against torsional twisting. A unique "clam-shell" style lower strut extension preserves factory strut use and alignment, using TCT lower bushings for a precise pivot. New tubular upper control arms with TCT pivot bushings replace OE stamped steel arms, enhancing strength and durability. The rear lift includes 5" tall fabricated steel blocks with integrated bump stop landings and an add-a-leaf, along with new Bilstein 5100 series rear shocks.
