Air Lift LoadLifter 5000 Rear Leaf Spring Air Helper Spring Suspension Leveling Kit

The Air Lift LoadLifter 5000 series is a premium air helper spring system engineered for trucks, vans, SUVs, and motorhomes that regularly haul or tow heavy loads. Designed to work alongside your existing leaf spring suspension, the LoadLifter 5000 delivers up to 5,000 pounds of leveling capacity, allowing you to safely maximize your vehicle's load-carrying capability up to the manufacturer's Gross Vehicle Weight Rating (GVWR).

Adjustable Air Spring Technology:

LoadLifter 5000 kits install between the vehicle's frame and the factory leaf spring suspension, providing fully adjustable air pressure support from 5 to 100 PSI. This on-demand adjustability lets you dial in exactly the right level of support for any load condition—increase pressure when hauling or towing, then reduce it when running light for a smoother everyday ride. The result is a level vehicle stance, improved braking performance, proper headlight aim, and significantly reduced stress on factory suspension components.
