A piston (16) for an internal combustion engine is disclosed. The piston body (34) has two pin bores (52) for receiving a piston pin. At least one rib (62) is disposed on the second side (38) and extends outwardly therefrom. The at least one rib is aligned laterally between the two pin bores in a direction along the piston pin axis. The at least one rib has a longitudinal axis (64) extending perpendicular to both the reciprocation axis (48) of the piston and the piston pin axis. A piston having a boss extending approximately within the piston pin radius of the piston pin axis, and a piston having a boss following the contour of the piston pin are also disclosed. An engine having the piston is also disclosed.
