I've got a set of KS pistons and no rings as I stole them to run on some Right Way Ind. pistons....which was extremely successful, by the way. The KS rings are VERY hard...but, they sealed up very well for me. I thought that might not be the case.
I don't need these bare pistons as I have so many rebuilt engines gathering dust...but, can't imagine letting them go for less than $250 and you made absolutely NO effort as to telling where you are located. So, you would need to pay freight above and beyond.
Dry-stored pistons in original box, pins, and retainers.....yes, oil cut-out models.
A set of Goetze rings would be superb on these from autohausaz.com
