About this part

Product Details

Mahle OE Performance Napier Steel 2nd Ring Set is designed for engine builders and performance applications. This set features a 4.170-inch bore size with a 1.0mm thickness for the second ring, utilizing a Napier design for improved oil control and reduced blow-by. The steel construction offers durability for demanding engine builds.

These rings are a popular choice for those rebuilding engines where precise sealing and efficient oil management are critical. The Napier profile on the second ring helps to scrape oil from the cylinder wall on the downstroke, preventing it from entering the combustion chamber. This bulk pack contains 48 rings, making it suitable for multiple engine builds or professional shops.
