    SBT oversized piston rings?

    Got 3 oversized pistons ready to install from SBT in a 4Tec NA motor. The rings are not labeled and its obvious which ones the oil ring. I have a metal colored ring and a black ring left. Would the silver ring be the top ring in this case? There are numbers on the 2 rings, but no markings like TOP. Thanks.

    I believe the oil ring is three separate pieces.....the 2 metal colored rings are your 2 top compression rings and should have a bevel on them.......I'm pretty certain the 2 blacks sandwich the waffle shaped scraper ring.......Pretty sure the bevel should be facing up

    You are correct on the oil ring being 3 pieces. I will check the other two rings. They look identical but one has a black outer edge and the other has a metal colored outer edge. Thanks.

    the thicker of the two is the top ring
