The Air Lift 77355 LoadLifter 5000 ProSeries Air Spring Kit is a premium rear suspension upgrade engineered for 2021 and newer Ford F-150 trucks in both 2WD and 4WD configurations. Designed for drivers who regularly tow or haul heavy loads, this kit delivers up to 5,000 lbs of load-leveling capacity to keep your truck riding level and in control.
