A vehicle axle is provided with a main body defined by the combination of a channel having an inverted U-shaped configuration and a bottom plate. The ends of the main body are curved upwardly to define a pair of gooseneck portions. Axle head sections are formed at the ends of the axle and are closed off by end extensions extending from the front and rear walls of the channel and a cover flap extension extending from the top wall of the channel. A head plate having a rounded back edge and/or a pocket is inserted within the space between the cover flap and the top edges of the end extensions.
