The premium complete 7″-8″ adjustable height front / 5.0″ rear Lift Kit for 2011-2019 Chevy Silverado/GMC Sierra 2500HD/3500HD 2WD/4WD System kit is specifically designed to give you a quality lift and rugged off road strength while maintaining the factory ride on the street. The complete kit 44-3072 Includes Bilstein Shocks and tubular Upper Control Arms. This system features precision-designed laser-cut and CNC formed sub-frame assemblies that directly bolt in. Includes custom formed nodular iron knuckles engineered to provide perfect geometry, ride and handling performance. Includes an integrated differential drop bracket system to ensure correct CV axle angles on 4WD applications and maximum performance in 4WD mode. Front lift is provided by ReadyLIFT Forged Torsion keys. This system provides adjustable lift from 7″ to 8″ while maintaining the factory ride. To lift the rear, this system includes OEM quality cast iron 5.0″ tall rear block that doesn’t sacrifice ride quality. Kit includes tough steel bump stop extensions, skid plate, and sway bar end links. Stock 20″ wheels OK or 9″ wheel w/ 4.75″ – 5.5″ BS – Stock 17″ or 18″ cannot be run with this system. The sub frame and other components are powder coated with a unique and improved Plascoat finish. The Plascoating on the components is a performance polymer alloy coating specifically designed to provide a long-lasting, tough coating for exterior applications. The Plascoat finish is especially resistant to stress cracking with improved abrasion and impact resistance as well as a great way to protect against adverse weather conditions, detergents, salt spray and other typical airborne pollutants. NOTE: SRW (Single Rear Wheel) models may require custom U-Bolts to accommodate factory tow package. Will not fit DRW (Dual Rear Wheel) applications without custom U-bolts. Towing Capacity will be reduced with the installation of this kit. NOTE: This kit is primarily designed to only be driven in 2WD at speed on public roads and that 4WD is only to be used off-road or in adverse slow speed conditions due to drive line vibrations at high speeds. Double cardan driveshaft may be required to help eliminate some of the high speed 4WD front driveline vibration when kits are 5-8″ high.
Tire Fitment:Â 37″ Maximum tire diameter
37×12.50 for no rub on a 9″ wide wheel with -6 offset
18″ – 37X12.5R18
20″ – 37X12.5R20
22″ – 325/60R22
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.
