Abstract
A lift axle is pivotally mounted to the frame of a vehicle for selectively providing additional flotation for the vehicle. A pair of frame brackets are secured to the frame members of the vehicle and have horizontally disposed mounting plate portions adjacent the lower ends thereof which have transversely extending bolt slots formed therein. First and second trailing arm mounting brackets are positioned below the first and second frame brackets, respectively, and have bolt openings provided in an upper mounting plate portion thereon to enable bolts to adjustably secure the trailing arm mounting brackets to the frame brackets. The lift axle suspension system is operatively connected to the mounting brackets. The connection of the first and second mounting brackets with respect to the first and second frame brackets permits the lift axle assembly to be mounted on frame members having varying distances therebetween and having varying frame thicknesses.
