F450/F550 Commercial Chassis Cab 1994-2026 Ford - Rear LoadLifter 5000 Air Bag Kit by Air Lift

The Air Lift LoadLifter 5000 57345 kit is built to handle the most demanding towing and hauling tasks, offering up to 5,000 lbs. of load-leveling capacity for a safer, more controlled driving experience. Engineered for the Ford F450 and F550 Commercial Chassis Cab, this system integrates directly with your vehicle’s rear suspension to provide reliable support whether you're towing a trailer, hauling equipment, or carrying heavy loads daily.

These durable air springs are fully adjustable from 5 to 100 PSI, allowing you to fine-tune your ride for any situation—loaded or unloaded. By restoring proper ride height, the kit helps prevent rear-end sag, improves steering and braking response, and realigns headlights for better visibility. Whether you're hauling a camper, towing a trailer, or managing commercial loads, the LoadLifter 5000 ensures a level, stable, and confident ride. Designed for longevity and performance, this rear air spring kit requires 9 inches of clearance between the tire and frame for installation and may require drilling depending on the specific application. Perfect for work, recreation, or heavy-duty use, the LoadLifter 5000 brings comfort, stability, and enhanced safety to every haul.
