Designed for 2013-2016 Ram ProMaster 1500, 2500, and 3500 model rear-wheel- drive vehicles, Air Lift's LoadLifter Series air spring kits work with existing suspensions to deliver up to 5,000 pounds of leveling capacity.
The air springs eliminate sagging and bottoming out when towing or carrying heavy loads, the company says. LoadLifter 5000 is the company’s heaviest-rated air spring kit and is engineered for hauling or towing heavy loads. LoadLifter 5000 Ultimate adds an internal jounce bumper for added shock absorption and extra protection for heavy loads. The jounce bumper also allows the air springs to be operated with zero air pressure. Units may be installed without drilling into a vehicle’s frame. Automatic, wired and wireless on-board air compressor systems are available to provide one-touch control of air springs from inside the vehicle or remotely.
