Mahle uses plasma-moly steel for these top compression rings, a well-known material for its durability and ability to create a strong seal against the cylinder wall. This construction helps maintain consistent compression, which is crucial for engine performance and longevity. The plasma-moly coating offers improved wear resistance, ensuring these rings hold up under operating conditions. They are designed to fit right into the specified cylinder bore and piston groove, simplifying the installation process for experienced mechanics.

This bulk pack is a practical solution for those undertaking multiple engine builds or working on larger fleets. Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your specific engine's service manual for detailed installation procedures and specifications.
