What is the purpose of the moly coating on these rings?

The moly coating on the top compression ring is designed to reduce friction between the ring and the cylinder wall. This helps to improve wear resistance, especially during the engine's break-in period, and can contribute to a longer lifespan for both the rings and the cylinder bore.

How many rings are included in this bulk pack?

This is a bulk pack that includes a total of 48 rings. This quantity is suitable for engine builders working on multiple engines or larger projects.

Can these rings be shipped to California?

No, these rings are not CARB approved and cannot be shipped to California due to emissions regulations.
