The Air Lift LoadLifter 7500XL Ultimate is a heavy-duty rear load-leveling air spring kit for the Ford F-250/F-350/F-450 4WD 2017-2019. Rated up to 7500 lbs of load-leveling capacity and adjustable from 5 to 100 PSI - it eliminates squat - sag - trailer sway - and bottoming out when towing or hauling. The Ultimate design adds an internal closed-cell-urethane jounce bumper so the springs are safe to run at zero pressure if air is ever lost. The 2-ply fabric-reinforced air springs install with common hand tools and no frame drilling - and are backed by a limited lifetime warranty.
