Air Lift – LoadLifter 7500 XL Ultimate Rear Air Spring Kit – 2020–2022 Ford F-250 & F-350 SRW 4WD – 57552

The Air Lift LoadLifter 7500 XL Ultimate Air Spring Kit (57552) is engineered for heavy-duty towing and hauling on 2020–2022 Ford F-250 and F-350 Super Duty Single Rear Wheel (SRW) 4WD trucks. Designed to handle demanding payloads, this rear air spring kit delivers up to 7,500 lbs. of load-leveling capacity, helping eliminate squat, reduce trailer sway, improve braking performance, and prevent bottoming out.

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

The system mounts under the frame, installs with no drilling required, and is designed specifically for SRW models, making it an ideal solution for serious work and towing applications.
