About this part

Product Details

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is key to good compression and oil control. This Mahle OE Performance Napier Steel 2nd Ring is designed to help seal the combustion chamber and scrape oil from the cylinder walls.

The Napier hook design on this second ring helps it to better scrape oil on the downstroke, while the steel construction offers solid durability. It's a plain ring, meaning it doesn't have any special coatings or treatments beyond what's needed for its basic function, making it a straightforward replacement part. This ring measures 4.255 inches in diameter and is 1.0mm thick with a 0.136-inch groove width.
