A height control valve assembly for an axle/suspension system of a vehicle includes a height control valve in fluid communication with a compressed air source, with at least one air spring of said vehicle, and with atmosphere. The height control valve is attached to the frame of the vehicle and includes a flow control means for regulating fluid flow through the valve. A control arm is operatively attached to the flow control means, whereby movement of the control arm regulates fluid flow through the height control valve. The height control valve assembly further includes a link having a first end and a second end. The first end of the link is operatively attached to the control arm. The second end of the link is attached to the beam of the axle/suspension system, such that the ends of the link are generally vertically aligned.
