I ordered some speedpro plasma moly rings, and here's what I got;

I want to make sure .. these are NOT chrome rings, right? I don't know what a plasma moly finish is supposed to look like, but I know that I do NOT want chrome, and these look awful shiny to me.

The photos suck because they were very difficult to photograph. I would describe the cylinder wall facing surface as similiar in shine/quality to a nickel (the coin not the metal), and the rest of the ring surfaces are just black cast ironish looking.

thanks.

why not just look the PN up in a catalog or their web site, or are you thinking you got differant rings in the correct box.

the part number is correct for what I ordered (plasma moly rings), I just want to be sure that's what's in the box.

Maybe a little bit paranoid, but the motor this is going into is being rebuilt because the previous build never developed a ring seal for unknown reasons (suspected incorrect hone job).

So, I just want to be sure. rebuilding motors is fun, but not the same motor every few months.

They look correct to me. Only the TOP ring is anything special on ANY ring set. Second compression ring is always just plain cast or ductile iron, no facing material.

If it's a moly-faced ring you can tell because the moly compound is contained in a groove in the edge of the top ring like yours are. It looks like a peanut butter sandwich up close, if the bread was really thin. Plain ring material above and below (just a thin ridge) and the different-looking moly compound between the two, taking up 80% of the space on the edge of the ring.

Don't go by shinyness. You got the right rings.

got it. that's exactly the info I was looking for and the rings definately have this sandwich look you describe!

thanks.
