Mahle OE performance plasma moly steel top compression rings are built for demanding engine builds. These rings are designed for a 4.600-inch bore and feature a 1.0mm thickness, making them suitable for high-performance applications where precise sealing is critical. The plasma moly coating on the top compression ring offers improved durability and reduced friction, which helps maintain cylinder wall integrity and ensures consistent performance under stress.

This bulk pack contains 48 rings, ideal for engine builders or shops working on multiple engines or large-displacement V8s. The steel construction provides strength and resilience, while the 1.0mm thickness is a common specification for performance builds that require a specific compression ratio and sealing capability.
