Air Lift’s LoadLifter 5000TM air spring kit for the F-450 (#57349) provides a cushion of air and works with the existing suspension to deliver up to 5,000 pounds of load-leveling capacity and eliminate sagging and bottoming out. These fully adjustable air springs keep the F-450 stable, level and comfortable whether loaded or unloaded.

For maximum shock protection, the LoadLifter 5000TM ULTIMATE (#88349) eliminates the harsh jarring of rough roads while leveling the F-450 when towing or hauling heavy loads. Featuring rugged, durable components, both of these Air Lift underframe kits work with most in-bed hitch configurations and can be easily installed in approximately two hours with no drilling into the vehicle’s frame required.

To conveniently inflate and deflate the air springs from inside or outside the vehicle, Air Lift offers wired, wireless and automatic on-board air compressor systems to provide on-the-go control of air springs.

All Air Lift products are backed by an industry exclusive lifetime warranty which covers the entire contents of the air spring kit, and the company also ensures satisfaction with a 60-day, no questions asked, money-back guarantee on load support air springs and on-board air compressor systems. The new F-450 kits are available now at dealers across the country and internationally.
