Installing Piston!

The proper ring type for the wiseco 11:1 raptor piston is XS, not XH as indicated in by the 2005 catalog. Earlier catalogs will reflect the correct type. Check the top of your piston, if its stamped with "XH" then you're ok, but all of the wisecos I've seen (including mine) have "XS" on the head. I got the same XH rings shipped to me, the oil insert wont fit, they are the wrong design and the wrong size. The upper and lower rings were fine though. Like I said, check the top of your piston before you try to install anything.

$hit, your kidding right? I ordered the ring kit a month ago, cant remember the part number. Would you happen to have the # for the CORRECT ring kit?
Found the ring set part # 3937XH, thats for a std bore 11:1

The problem is the ring type, which we've already concluded is XS and not XH by the marking on the piston. Ring size and design are the same, its just the oil clip design and size that is the problem. That's what the letters signifiy, ring and oil assembly design. The numbers are the bore size.
You should need ring set 3937XS.
