The ReadyLift 44-3072 7"-8" Off-Road Series Lift Kit with Bilstein Shocks is one of the most rugged off-road lift systems for your 2011-2019 GM 2500HD/3500HD 2WD/4WD. This premium Off-Road Series Lift Kit is specifically designed to provide a quality lift and off-road strength while maintaining the factory ride on the street.
The complete kit includes Bilstein 5100 Series Shocks and tubular upper control arms. This system features precision-designed laser-cut and CNC-formed sub-frame assemblies that bolt directly in. It includes custom-formed nodular iron knuckles engineered to provide perfect geometry, ride, and handling performance. Additionally, it has 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 new ReadyLIFT Forged Torsion Keys, allowing adjustable lift from 7 inches to 8 inches while maintaining the factory ride. The rear lift is achieved with OEM quality cast iron 5.0" tall rear blocks that don’t sacrifice ride comfort, providing a total rear lift of 5.0 inches when installed. The kit also includes tough steel bump stop extensions, a skid plate, and sway bar end links.
All components are powder-coated with a unique and improved Plascoat finish. This finish 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, protecting against adverse weather conditions, detergents, salt spray, and other typical airborne pollutants.
Features:
- 7"-8" front lift
- 5" rear lift
- Special Plascoat finish
- Bilstein 5100 Series Shocks
- Uses ReadyLIFT torsion keys

- Wheel fitment: Stock 20" wheels OK or 9" wide wheel with 4.75 - 5.5 backspacing (Stock 17" or 18" wheels cannot be run with this system)
Application Notes:
- This kit is primarily designed for driving in 2WD at speed on the road, with 4WD intended for off-road or adverse slow-speed conditions due to driveline vibrations at high speed.
- A double cardan driveshaft may be required to help eliminate high-speed 4x4 front driveline vibration when kits are raised 6-8" high.
- There are many variations in manufacturer aftermarket tire and wheel combinations in width, actual diameter, tread pattern, etc. It is up to the installer to determine wheel and tire fitment on the vehicle and guarantee that there is no rubbing of the tire on any components, both inside and outside surfaces. The above guide is for reference only.
- Truck freight item: Allow 1-2 weeks for delivery. Shipping fees apply.
