The piston includes a piston body that extends along an axis from a crown portion to a skirt portion with a full piston skirt and to a pin boss portion. The piston body includes a plurality of ring grooves in the crown portion and at least one ring groove in the skirt portion. A wrist pin which has a length that is longer than a maximum diameter of the piston body is joined with the piston body at the pin boss portion and extends past the pin boss portion for receiving a pair of connecting rods on opposite sides of the piston body. The piston body is a monobloc piston body which is made of one integral piece or of multiple pieces that are welded or adhered together.
