What does 'moly faced' mean for these piston rings?

Moly faced means the rings have a coating of molybdenum compound. This coating is known to improve wear resistance, heat tolerance, and the sealing capabilities of the piston rings.

What is the significance of the .010in sizing?

The .010in designation indicates that these rings are 0.010 inches smaller than the standard size. This is typically used when cylinder walls have been honed or bored out to a specific oversize during an engine rebuild.

Can these rings be shipped to California?

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

Product Details

These S&S Cycle piston rings are moly faced, meaning they have a coating of molybdenum compound. This advanced coating is known for improving wear resistance, helping the rings last longer under demanding conditions. It also boosts heat tolerance, which is crucial for keeping engine temperatures in check, and helps create a better seal between the piston and cylinder wall. This set is specifically sized at .010 inch, which is an important detail if you're rebuilding or replacing pistons in your Big Twin engine from 1984-1999.

When you're working on the heart of your motorcycle, using well-made components like these moly-faced rings can make a notable difference in engine performance and longevity. The molybdenum compound helps reduce friction, which contributes to better sealing and more efficient combustion. This means your engine can run smoother and potentially last longer between rebuilds. It’s a solid choice for anyone looking to ensure their engine is properly sealed and protected.
