The Air Lift LoadLifter 5000 Ultimate is a rear load-leveling air spring kit for 2006-2017 Ford E-450 Super Duty chassis. It works alongside the factory leaf springs to add up to 5,000 lbs of load-leveling capacity, keeping the vehicle level and stable whether loaded or unloaded. The closed-cell urethane jounce bumper sealed inside each air spring absorbs shock and lets the kit run safely at zero air pressure. Air pressure is adjustable from 5 to 100 PSI and installation requires no drilling into the frame.
