Offering up to 7,500 pounds of load-leveling capacity, the new LoadLifter 7500 XL kit from Air Lift Company will make towing and hauling with your Ford F-250, F-350, and F-450 4WD a comfortable and stress-free experience. For frequent use, our fully-adjustable, industry leading air springs are the perfect partner for your vehicle, eliminating any issues that you might face. The new LoadLifter 7500 XL kit helps to eliminate problems frequently faced when towing and hauling, such as squat, poor headlight aim, trailer sway, body roll, and bottoming out through the use of massive 7-inch, double-convoluted bellows air springs. These air springs provide all the benefits of similar systems, but with the ability to do the same job at a lower air pressure, providing a more comfortable ride. With the ability to adjust the air pressure from 5-100 PSI, your Ford Super Duty can be ready for any weight and any situation. The added stability and weight-distribution provided by air springs allow you to tow and haul safely, knowing that you have optimal braking and steering control. An Air Lift exclusive, each kit comes equipped with upper and lower roll plates, added to protect the air springs from sharp edges, while increasing the load capacity by 10%. The air springs themselves are built like a tire, reinforced with 2-ply fabric for maximum strength. All of the end caps are made with an ultra high-strength nylon composite formula, strong as steel but much lighter and corrosion proof. As the leader in air suspension products for 70 years, Air Lift is committed to delivering quality load support parts that last. To ensure the highest quality, longevity, and customer satisfaction, the key suspension components, including the air springs and all hardware, have all been torture-tested to 1 million cycles on our hydraulic test rig. Never exceed vehicle's Gross Vehicle Weight Rating (GVWR).
