tend to run OEM with OEM. others may be made different thickness, Nice Idea to save a little money but how much do you really save when something might happen. Just my 2cents
I hear ya, I have always done that too, OEM with OEM, however, I just noticed the aftermarket listed them as OEM replacements and even showing the OEM part numbers with them....
I guess the true way to find out is to mic a oem and a aftermarket and see what they look like together and see what type of material they are. Some times they will use something that is of lesser quality.

I'm currently running rings from Parts Unlimited on Yamaha OEM pistons in my Phazer. Fit was perfect, end gap perfect, no issues.

I have done it many times and I have never had a issue ............for many of my vintage sleds there are no OEM rings out there and if you do find them they are priced so that but the time I buy a pair of oem I could have bought 8 aftermarkets for the same price this is on the single ring pistons .............I find SPI rings to be good quality ....
