About this part

Product Details

These Mahle OE steel Napier 2nd rings are built for a 4.250-inch bore, with a .043-inch thickness and a .135-inch width. The Napier hook design in the second ring helps to scrape oil from the cylinder wall, which is crucial for preventing oil consumption and blow-by. This bulk pack contains 48 rings, making it a solid option for engine builders working on multiple projects or high-volume rebuilds.

Mahle is a well-known name in engine components, and these rings are made from durable steel, chosen for its strength and ability to handle the heat and pressure inside an engine cylinder. The plain finish means they are ready to install without special coatings, and the precise dimensions ensure a good seal against the cylinder wall. This attention to detail helps maintain compression and keep oil where it belongs.
