The Midland Haldex 90554334 is a Type CR Controlled Response Height Control Valve with an integrated dump valve for air suspension systems. All ports are 1/8" NPT, and the unit ships with 1/4" and 3/8" fittings included. The dump valve is normally open, meaning it requires air pressure to hold the suspension up and releases air from the air springs when that pressure is removed, lowering the vehicle for easier loading and unloading. The suspension dump control can be operated from the cab or plumbed to activate automatically when the emergency brake is set. Also listed under cross-reference numbers MD90554334, HDX90554334, and AC002D. A genuine Midland Haldex part sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
