A piston for an internal combustion engine comprising: a crown having a crown outer side and a crown inner side; a skirt extending from the crown, the skirt having a skirt outer side and a skirt inner side, the skirt defining a reciprocation axis of the piston; first and second pin boss assemblies connected to the crown inner side and the skirt inner side, the first and second pin boss assemblies defining a pin bore axis perpendicular to the reciprocation axis, the first and second pin boss assemblies being adapted for receiving a piston pin having a piston pin axis with the piston pin axis being coaxial with the pin bore axis, the first and second piston boss assemblies being disposed on opposite sides of the reciprocation axis and being spaced apart in a direction defined by the pin bore axis, each of the first and second pin boss assemblies comprising: a pin boss defining a pin bore, the pin bore defining the pin bore axis; a rib extending from the crown inner side toward the pin boss, the rib being generally aligned with the pin boss in the direction defined by the pin bore axis, the rib extending along the crown inner side along a direction generally parallel to a lateral axis of the piston, the lateral axis of the piston intersecting and being perpendicular to the reciprocation axis and the pin bore axis, a central strut extending from the pin boss to the crown inner side in a direction generally parallel to the reciprocation axis, the central strut being generally centered relative to the pin bore axis; a first diagonally extending strut having a first end connected to the pin boss and a second end connected to a junction of the crown inner side and the skirt inner side; and a second diagonally extending strut having a first end connected to the pin boss and a second end connected to the junction of the crown inner side and the skirt inner side, the first and second struts being disposed on opposite sides of a plane containing the reciprocation axis and the pin bore axis. a crown having a crown outer side and a crown inner side;
