Air Lift – LoadLifter 7500 XL Ultimate Rear Air Spring Kit – 2011–2016 Ford F-250 & F-350 Super Duty 4WD – 57596

The Air Lift LoadLifter 7500 XL Ultimate Air Spring Kit (57596) is built for heavy-duty towing and hauling on 2011–2016 Ford F-250 and F-350 Super Duty 4WD trucks, delivering up to 7,500 lbs. of load-leveling capacity. Designed to handle the most demanding loads, this rear air spring kit helps eliminate squat, reduce trailer sway, improve braking performance, and prevent bottoming out.

Part of Air Lift’s Ultimate series, this kit features an internal jounce bumper, allowing the air springs to be safely run at zero PSI without damage—providing full-time suspension support even when unloaded. By leveling heavy loads with less air pressure, the LoadLifter 7500 XL improves ride comfort while reducing stress on factory suspension components.

This system installs with no drilling required and mounts under the frame for a clean, secure fit. It is compatible with single rear wheel (SRW) and dual rear wheel (DRW) trucks, works with most side-mount fifth wheel hitch applications, and is specifically designed to fit the factory in-bed hitch system.
