What is the primary function of these piston rings?

These piston rings create a seal between the piston and the cylinder wall. This seal is essential for maintaining compression within the cylinder, controlling oil consumption by preventing it from entering the combustion chamber, and helping to transfer heat from the piston to the cylinder wall.

What does the .043" and 3/16" sizing refer to?

The .043 inch measurement refers to the gap of the top compression ring. The 3/16 inch measurements refer to the width of the second compression ring and the oil control ring.

Why are these rings not CARB approved?

Some engine components are not approved by the California Air Resources Board (CARB) due to emissions standards. This means they cannot be legally sold or shipped to California for use on vehicles registered in that state.
