The shoulder has a high wear region and a low wear region disposed opposite from the high wear region, wherein the low wear region has a first hardness that is less than a second hardness of the high wear region. Generally, the high wear region extends circumferentially around the shoulder and is between about 90 degrees counter clockwise to about 90 degrees clockwise measured from a center point on the shoulder facing inward toward a center part of the body.
