Yes I have searched for piston rings on this board but I have not been able to find anything on stock rings. The stock pistons are metric 2.0 1.5 4.0 and the rings that have been suggested on many threads I have not been able to find in metric sizes. aka SpeedPro these are suposidly one of the best sets that you can get. But Again I can not find them in metric. Now there is a Sealed Power ring set that you can get at Advanced and NAPA that are made by the same manufacture. I guess my question is am I limited to EOM Hastings or these Sealed Power rings... or are there any more sets out there that are better for the stock pistons?
