LANSING, Mich. - Whether your Ram ProMaster serves as a cargo van or a commercial work truck, Air Lift's heavy-duty LoadLifter 5000(tm) (part #57233) and LoadLifter 5000(tm) ULTIMATE (part #88233) adjustable air spring kits are designed to support and protect your load, no matter the pavement ahead. 
Designed for 2013-2016 Ram ProMaster 1500, 2500 and 3500 model rear-wheel- drive vehicles, Air Lift's LoadLifter series air spring kit works with your existing suspension to deliver up to 5,000 pounds of levelling capacity. The air springs eliminate sagging and bottoming out when towing or carrying heavy loads, while providing a safe, comfortable ride.
LoadLifter 5000 is Air Lift's heaviest-rated air spring kit and is specifically engineered for hauling or towing heavy loads.  LoadLifter 5000 ULTIMATE offers all the benefits of the LoadLifter 5000 but its exclusive internal jounce bumper provides added shock absorption and extra protection for heavy loads. The jounce bumper also allows the air springs to be safely operated with zero air pressure.
Featuring rugged, durable components, including air springs and all hardware, both the LoadLifter 5000 and LoadLifter 5000 ULTIMATE offer a fast, straightforward installation and requires no drilling into the vehicle's frame. For convenient inflation and deflation of the air springs, Air Lift offers automatic, wired and wireless on-board air compressor systems to provide one-touch control of your air springs, from inside the vehicle or remotely.
