Air Lift LoadLifter 5000 Ultimate Plus Air Spring Kit

The Air Lift LoadLifter 5000 Ultimate Plus is Air Lift's flagship load-support air spring system, purpose-built for truck and van owners who demand the highest level of towing and hauling performance. Mounting to the vehicle's existing leaf spring suspension with no permanent modifications required, each kit in this product line delivers up to 5,000 pounds of load-leveling capacity to eliminate rear squat, trailer sway, body roll, and compromised headlight aim when operating under heavy loads.
