Product Details
This is a bulk pack of 48 Mahle OE Performance Napier Steel 2nd Ring sets. Each set is designed for a 4.020-inch bore with a 1.0mm ring width and a 0.136-inch thickness. These rings are a plain steel design, intended for performance engine builds where precise ring seal is critical.
Mahle is a well-known name in engine components, and these Napier-style second rings are built for durability and consistent performance. The Napier design helps to reduce oil consumption and blow-by by creating a more effective seal against the cylinder wall, especially as the piston changes direction. The steel construction offers good strength and resistance to wear under demanding operating conditions.
This bulk pack is ideal for engine builders or shops working on multiple performance engines. Ensure you have the correct bore size and ring dimensions for your specific application before ordering.
