A rough duty air-suspension system for trucks and the like wherein a pair of lengthwise radius rods normally retain the axle in place and align it, while a transverse radius rod, or tracking rod, prevents the axle from shifting sideways with respect to the vehicle; at the same time a unified cantilever beam combination of a leaf spring and air spring supports the load. If either of the lengthwise radius rods should break, the leaf spring is provided with a safety hook for preventing serious displacement of the axle. Leaf spring loading is equalized by shims secured between the leaf spring and the truck frame.
