Offering up to 7,500 pounds of load-leveling capacity, the LoadLifter 7500 XL Ultimate kit for the 2023-2025 Ford F-450 4WD from Air Lift will make towing and hauling a comfortable and stress-free experience. Our fully adjustable, industry-leading air springs are the perfect upgrade for your vehicle and work to eliminate any issues you might face when towing and hauling, such as vehicle squat, poor headlight aim, trailer sway, body roll, and bottoming out. While maintaining exclusive features from our other systems, including roll plates for added protection and ultra-high-strength composite formula end caps, what sets the LoadLifter 7500 XL kit apart is a pair of massive 7-inch, double-convoluted bellows air springs. The larger air springs allow for greater leveling abilities at lower air pressures compared to similar systems, keeping your cargo safe and secure while ensuring a more comfortable ride. Installing the kit is simple, requiring only common hand tools and no frame drilling. The LoadLifter 7500 XL Ultimate kit has clear, easy-to-follow instructions and an underframe design that works with most in-bed hitches. As the leader in air suspension products for over 75 years, Air Lift is committed to delivering quality load support products that fit, work, and 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. With a limited lifetime warranty, a 60-day ride satisfaction guarantee, and a dedicated in-house customer service team, you can purchase this kit with peace of mind. Do not exceed the vehicle’s gross vehicle weight rating (GVWR). Internal jounce bumper absorbs shock and can be safely run with zero PSI.
