The Air Lift LoadLifter 5000 Ultimate is a rear load-leveling helper air spring kit for the 2016-2020 Ford F-150 Raptor 4WD. It adds up to 5,000 lbs of leveling capacity to eliminate squat, trailer sway, and bottoming out when towing or hauling. Double-bellows air springs are adjustable from 5-100 PSI, and an internal closed-cell jounce bumper lets the kit run safely at zero PSI. This underframe-mounted kit requires professional installation, including drilling and cutting.
