Wiseco pistons are marked. A small logo is cast into the inner cavity, sometimes on the piston pin boss.

From what I understand, they are interchangeable.

are the ring's the same. I need to order new ring's but I don't know what kind of piston's I have!
Do oem ring's work on pro-x piston's?

i know pro-x rings work on oem pistons, cuz thats what im running right now. i dont think you should have a problem...not sure about wisecos being the same.
