ReadyLIFT offers the new Big Lift Kit for 2019-2023 Chevy Silverado and GMC Sierra 1500 trucks, specifically the 8 InchF-6.5-Inch R Big Lift Kit (44-3985) for 4WD models. 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-Inch 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-Inch tall fabricated steel blocks with integrated bump stop landings and an add-a-leaf, along with new Bilstein 5100 series rear shocks.

Extensive testing ensures this 8-Inch lift kit enhances the ride quality of the new GM 1500 4WD trucks. Recommended tire sizes are 37x12.50 on 20x9 0 offset wheels with no trimming, and 37x12.50 on 20x10 -18 offset wheels with minor trimming.

Trimming areas include the front valance, felt liner edges, and mud flap. The use of the Auto 4 Hi feature is not recommended with this kit.

Key features include maintaining factory ride and handling, clearance for up to 37x12.50 tires on an 8-inch kit, the proprietary lower strut clamshell design, tube steel upper control arms with maintenance-free pivot bushings and 1-ton ball joints, 3/16-inch steel plate cross members and skid plate, anti-torsion differential drop brackets, fabricated steel rear lift blocks, and premium Bilstein rear shocks.

Pleasantly surprised!
Color: Beige, Size: 35" x 23"x 3.5"
This bed is thick, plush, soft and has both a furry plush side and a cooler canvas side. It's the perfect size for my dog's crate and he does seem to really enjoy laying on it. It's super easy to clean - washes up nicely on delicate and with a low tumble dry. I had no issues waiting for it to fluff up after being unpackaged, too. It was good to go by that evening. I was expecting, at this price point, something flimsy with loose threads. Overall, I think it's much thicker and nicer than I was expecting for the price! Thinking about grabbing another one before they disappear!

Thick and soft

We and the corgis love the bed. We got the large size so that both corgis could be on it together so the large size is perfect for 2 small to medium breed dogs that like to snuggle/sleep together. The bed is surprisingly thick and soft and well made. It appears that it will be fairly easy to machine wash and dry and I suspect if the pups do not decide to demolish it like they do their stuffy toys, it will last a good long time. It is definitely a good buy for the money.
