Abstract
Systems and apparatuses include a tag axle system including an axle assembly, a linkage coupling the axle assembly to a vehicle chassis, and a hydraulic cylinder coupled between the vehicle chassis and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position, and acts as a spring damper suspension component.
