Abstract: A pair of front couplings and a pair of rear air spring over shocks couple the cab to the vehicle frame. A motion control link includes a central base and pair of arms extending longitudinally from the central base. A base coupling directly couples the base to the vehicle frame. A rear arm coupling for each arm directly couples the arm to the rear of the cab. The rear base coupling and the rear arm coupling essentially restrict lateral movement of the motion control link and permit tuned lateral movement of the frame relative to the rear of the cab to provide lateral motion control at the rear of the cab. The motion control link defines an arc that intersects the front coupling arc. The rear arm couplings include a rear elastomeric bushing member including voids to accommodate for the intersecting arcs.
