I'm rebuilding my top end with all OEM parts. I noticed that one ring is a dark gray color and the other is kind of a bronze-ish color. Which one goes on top? It's an '08 450. Thanks in advance! Bill

The compression rings are two different thicknesses, and only one of the them will fit in the top groove. The more silver colored ring should be the top.
