This air-ride steering suspension continually equalizes weight, even in the event of a loss of air pressure. The unit offers up to 46,000 lbs. load capacity per tandle axle grouping. The four-corner axle alignment helps extend tire life. The suspension works with minimal air pressure, resulting in a softer ride and reduced driver fatigue.
