A hitch step assembly comprises a first shot component injection molded from a first polymer compound with a high flexural modulus and a second shot component injection molded from a second polymer compound having a lower flexural modulus relative to the first shot compound. A post and a step body core are molded from the first polymer compound. A shell of the step body is molded from the second polymer compound and is overmolded onto the step body core. The shell forms a compression zone that attenuates rear impact forces the hitch step encounters, thus offering some protection against rear impacts. The hitch step assembly exhibits satisfactory resistance to deflection and torsional bending about a hitch receiver axis when a force is applied on the top surface of the hitch step near its lateral ends.
