Mahle Rings Perf Napier Steel 2nd Ring 4.145in x 1.0MM .136in RW Plain Ring Set (48 Qty Bulk Pack)

This bulk pack gives you 48 Mahle Performance Napier Steel second rings, each measuring 4.145 inches in diameter with a 1.0mm thickness and a .136 inch width. These rings are designed for performance engine builds where precise ring seal is critical for power and efficiency. The Napier style second ring has a unique shape that helps it seal better against the cylinder wall, especially during the power stroke, and the steel construction offers good durability for demanding applications.

Mahle is a well-known name in engine components, and these rings reflect that reputation for well-built parts. The Napier design is a popular choice for builders looking for improved oil control and blow-by reduction compared to standard ring designs. Because this is a bulk pack of 48 rings, it's ideal for shops or builders who frequently work on engines that use this specific ring size and style, ensuring you have them on hand when needed.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific build requirements and manufacturer recommendations to ensure proper installation and performance.
