What is the primary function of piston rings?

Piston rings serve two main jobs: they seal the combustion chamber to prevent gases from leaking past the piston, and they help control the amount of oil that reaches the cylinder walls for lubrication.

What does the '1.5,3mm' in the product name refer to?

This refers to the dimensions of the rings. The '1.5mm' is the thickness of the top compression ring, and the '3mm' is the thickness of the oil control ring. This is a common size for many performance engine builds.

Can these rings be shipped to California?

No, these piston rings are not CARB approved and cannot be shipped to California due to emissions regulations.
