ReadyLIFT's all-new 44-30801 8" lift kits with ReadyLIFT SST3000 shocks are a great option for the customer who wants a taller, lifted height and the ability to run up to 38" tall tires. The 44-30801 lift kits include laser-cut, fabricated heavy-duty steel cross-members, new cast iron OE-style knuckles with the perfect geometry built-in, torsion arm brackets, popular fabricated steel upper control arms with corrected ball joint angles, taller fabricated steel rear lift blocks and new forged torsion keys with the proper amount of indexing. . These new torsion bar relocation brackets eliminate the traditional lowering of the torsion bars, which can inhibit ground clearance from a lift installation and help to improve the overall driving experience. Additionally, each kit includes crucial differential drop brackets and CV axle spacers, 12" sway bar end links, bump stop extensions, OE style cast iron rear lift blocks, heavy-duty steel skid plate, and finally, SST3000 series shocks.

NOTE: Some GM HD trucks equipped with Tow Package may require custom-length U-bolts purchased separately. Custom U-bolt length may vary by vehicle application. If the ReadyLIFT kit's standard U-bolts are too short, ReadyLIFT recommends locally sourcing custom U-bolts built to each truck's specifications.



38" Maximum tire diameter

38x12.50 for no rub on a 9" wide wheel with 0 offset

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.



Please read Instructions thoroughly and completely before beginning installation. Installation by a certified mechanic is recommended.

Estimated Installation Time: 12 Hours +/- 1 hour (excluding alignment and wheel/tire assembly)
