A lift axle suspension includes an axle and a first suspension air bag acting one of directly or indirectly in a downward direction upon the axle. A lever is provided having a first end, a second end, and a fulcrum selectively positioned between the first end and the second end. The first end is linked to the axle. A second lift air bag acts in a downward direction upon the second end of the lever. This causes the lever to pivot about the fulcrum such that the first end of the lever, which is linked to the axle, is raised. An air diverter selectively supplies air to either the first suspension air bag to lower the axle or the second lift air bag to raise the axle.
