I am looking piston rings can somebody tell me what the thicknesses are because I’ve bought the ones from autos one and none of them fit in the grooves in my piston

thanks

I have chosen one only problem is I can’t seem to just buy one set of rings for one piston in this particular case from Rock-auto.

Don't feel bad, I am a 61 yr old with lots of mechanical experience and lots of engine rebuilding under my belt and it took me 3 tries at rings until I figured it out. Worst thing is that they sell both SAE and Metric for the same year engines. After 3 sets not fitting (and sellers not even telling me there was a metric version) I finally found one seller that had both listed in the same listing and said I must say which size when ordering.

I have a 1995 f150 5.8. I was told I need a stock piston ring. In a 4in ring. They won't tell me any other info. It has a 88yr block from the factory. I think I found the same part as listed above. Is this the part I need also?
