A piston includes an annular body including a crown portion defining a longitudinal axis, a radial direction perpendicular to the longitudinal axis, and a circumferential direction. The crown portion includes a top squish surface, and a circumferential annular wall extending downwardly axially from the top squish surface as well as a skirt. A first piston ring receiving groove is spaced away from the top squish surface, an upper land and a lower land extend from the first piston ring receiving groove, and a bottom blend connects the lower land to the first piston ring receiving groove.
