Mahle Rings Perf Steel Napier 2nd Ring 3.902in x 1.0MM .136in RW Plain Ring Set (48 Qty Bulk Pack)

These Mahle OE performance steel Napier second rings are built with a 3.902-inch bore diameter and a 1.0mm thickness, featuring a unique Napier hook design. This design helps to scrape oil from the cylinder wall more effectively than a conventional ring, which can lead to improved oil control and reduced oil consumption. The plain ring finish ensures a solid seal against the cylinder wall, contributing to better compression and overall engine performance.

This bulk pack contains 48 rings, making it a practical choice for engine builders or shops working on multiple engines. Mahle is a well-known name in engine components, and these rings are made to meet the demands of performance applications where reliable sealing and oil control are critical. The steel construction offers durability and consistent performance under various operating conditions.
