Every piston includes the wrist pin and pin clips where required. Pistons are sold by bore size - standard for unmachined bores, with oversizes for blocks that have been bored and honed - so verify your finished bore diameter with a precision gauge before ordering, and always replace pistons and rings together during a rebuild. Enginetech has supplied engine rebuild components since 1983.
