The Air Lift LoadLifter 5000 Air Spring Kit (57399) is designed to improve towing and hauling performance on Ford Super Duty trucks, delivering up to 5,000 lbs. of load-leveling capacity. Built for durability and adjustability, this rear air spring kit helps eliminate squat, reduce trailer sway, improve ride quality, and prevent bottoming out when carrying heavy loads.
With fully adjustable air pressure from 5–100 PSI, the LoadLifter 5000 allows you to fine-tune ride height whether loaded or unloaded, providing a stable and controlled driving experience. This system is ideal for frequent towing, work trucks, and heavy payload applications, helping reduce strain on factory suspension components while maintaining proper vehicle stance.
Installation is bolt-on with no drilling required, and the kit is compatible with factory in-bed hitch systems and most side-mount fifth wheel hitch applications, making it a versatile solution for work and towing setups.
