Product Details
This is a Mahle OE steel Napier 2nd ring set, part number 3021361. These rings are designed for engine rebuilds where proper cylinder sealing is critical for performance and longevity. The Napier hook design in the second ring helps to scrape oil from the cylinder wall, preventing it from entering the combustion chamber, while also helping to maintain a seal against blow-by.
Mahle is a well-known name in engine components, and this ring set is built to meet the demands of a performance-oriented rebuild. The steel construction offers good durability, and the specific dimensions of 3.771 inches in diameter, 1.0mm thickness, and a 0.136-inch height are crucial for a precise fit within the piston groove. Proper installation is key to ensuring these rings function as intended, contributing to efficient combustion and reduced oil consumption.
