Control Boxes
Air suspension control boxes manage the fill and dump functions of your suspension system while displaying system pressure for quick diagnostics. Designed for trucks, trailers, buses, and RVs, these rugged enclosures protect internal air valves and components from weather, road debris, and damage. Used to manually exhaust the air from the suspension of an air ride trailer. Control boxes can be ordered with custom valving. An optional gauge indicates the air pressure in the suspension, which may be used to calculate load weight.
