5/27/2025
Get the best support for your 2024-2025 Chevy Silverado 2500 HD ZR2/2024-2025 GMC Sierra 2500 HD AT4X 4WD with the new LoadLifter 5000 Ultimate kit with Air Spring Cradles from Air Lift. With up to 5,000 lbs. of load support, this kit will make towing and hauling a comfortable and stress-free experience.
Our fully adjustable air springs are the perfect partner for your vehicle for the ultimate ride comfort and protection. They work to eliminate any issues you might face while towing, like squat, poor headlight aim, trailer sway, body roll, and bottoming out.
The kit also includes Air Spring Cradles, which allow the air springs to detach from the lower bracket for full suspension extension, ideal for overlanding and off-roading. With these air spring cradles, the LoadLifter 5000 Ultimate allows the complete use of the ZR2 and AT4X’s towing capacity, staying safe and comfortable.
The LoadLifter 5000 Ultimate's built-in internal jounce bumper, replacing the factory jounce bumper, sets it apart from other air spring kits.
Installing the kit is simple, requiring only common hand tools and no frame drilling. The LoadLifter 5000 Ultimate kit has clear, easy-to-follow instructions and an underframe design that works with most in-bed hitches.
*Do not exceed the vehicle’s gross vehicle weight rating (GVWR).
