Abstract
An adjustable run height lift axle suspension system includes an axle assembly, an air spring and a lift actuator. A device may be releasably attached to the axle assembly and connected to each of the air spring and the lift actuator, the device spacing the air spring away from the axle assembly. A selected one of multiple devices may be used, the suspension system having one run height when one device is releasably attached to the axle assembly and connected to each of the air spring and the lift actuator, and a different run height when another device is used. The air spring may have approximately the same operational height when the suspension system is at the different run heights.
