Upgrade the rear suspension of your 2023-2026 Ford F-450 Super Duty with the AIR LIFT LoadLifter 7500 XL Ultimate Air Spring Kit, part number 57579. Designed for heavy-duty load support, this complete kit includes air springs, vehicle-specific mounting brackets, air lines, and the hardware needed for installation. It helps provide adjustable support when hauling heavy loads or towing, while maintaining a more controlled and level ride than the factory suspension alone.
Built for demanding truck applications, the LoadLifter 7500 XL Ultimate system provides up to 7,500 pounds of load-leveling capacity when used properly. The adjustable air springs allow you to tune the support to match changing cargo and trailer demands, helping reduce rear-end sag, improve handling, and maintain more consistent headlight and steering alignment under load. The system is intended for the rear of compatible Ford F-450 Super Duty trucks and is engineered as a vehicle-specific suspension upgrade.
The included brackets feature a durable black powder-coat finish for added protection against everyday road exposure. AIR LIFT’s LoadLifter 7500 XL Ultimate design combines robust components with a practical installation package, making it a suitable choice for work trucks, towing vehicles, and owners who need additional rear suspension support. Confirm vehicle application and follow all installation instructions before fitting the kit. Part number 57579 is supplied as a complete air spring suspension kit for compatible 2023-2026 Ford F-450 Super Duty models.
