Abstract: A mounting plate secured to a vehicular axle includes an elevator plate adjustably spaced from the mounting plate employing plural pairs of toggle links, wherein the toggle links are actuated by a piston rod. The piston rod is arranged for retraction to the first toggle links to effect opening of the toggle links and their spacing of the elevator plate relative to the mounting plate. A pump structure is arranged to direct pressurized air to the piston mounted to said piston rod, such that upon deactivation of the ignition switch within the associated vehicle, the pump is deactivated to direct the piston and the piston rod in a spaced relationship relative to the first toggle link pair and project the elevator plate relative to the mounting plate and thereby elevate the vehicle axle relative to an underlying support surface.
