Does anyone know what material JE use in the pro seal ring packs? Skinny 1 mm x 1.2mm x 2mm.
And what final bore finish grit is best for them?

Re: JE pistons pro seal rings
As stated above, call JE for this information. JE used to source most of their high performance rings from Perfect Circle/MAHLE, not sure if they are still sourcing from them though.

The top ring is steel with a composite nitrite coating and the second is a cast iron material. Three piece oil ring chrome steel rails. Wiseco XC is the same.
