What does 'moly faced' mean for these piston rings?

Moly faced means the rings have a coating of molybdenum. This helps them wear better, tolerate higher temperatures, and seal more effectively in the cylinder.

What size bore are these rings intended for?

These rings are .010 inch oversize, meaning they are designed for engines with a cylinder bore that is 3-7/16 inches in diameter.

Can these rings be shipped to California?

No, these rings are not CARB approved and cannot be shipped to California.
