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 relatively low Shore D hardness but high elastic compression. 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 on the step body core. The shell forms a compression zone that provides some protection against rear impacts. The hitch step assembly exhibits satisfactory resistance to torsion around the hitch receiver axis and deflection, even when a width of the step body exceeds 10.7 inches and the weight of a large man is placed on the top surface of the hitch step near its end.
