Tow your 5th wheel or gooseneck trailer with an AirLift Loadlifter 5000 Ultimate air bag kit. Not only are these air bag systems going to make a more comfortable ride, they are going to provide you and your passengers with a safer ride by increasing your trucks handling and control while towing or hauling. Air Lift LoadLifter 5000 Ultimate air bag kits provide up to 5,000lbs of load-leveling capacity. Leveling a truck that's carrying a large load increases ride quality, as well as eliminating body roll, bottoming out, and squat. A truck that isn't level has reduced steering capabilities, poor braking, and can lead to trailer sway. Since the PSI in the air bags is adjustable, it is possible to inflate one side to a higher level to level uneven loads. Air Lift LoadLifter 5000 Ultimate air bag kits are constructed of a durable rubber and include roll plates to protect the air springs form possible abrasion and increase load capacity up to 10%. What makes these different then the 5000 series and the Ultimate are the jounce bumpers built into them. What this means is if a bag ever melfunctions the load will fall to the bumpers not leaving you stuck riding on the frame with a heavy load. A great safety feature. These kits are easy to install and includes all necessary brackets and hardware.
