What does the moly face coating do?

The moly face coating is a molybdenum compound that improves the ring's wear resistance and heat tolerance. This helps the rings last longer and perform better under demanding conditions.

What does '.090in' mean for these piston rings?

The '.090in' indicates that these rings are 0.090 inches larger than the standard size. This means your engine's cylinders must be bored out to this specific oversize to ensure a proper fit and seal.

About this part

Product Details

If you're rebuilding the top end of your 1966-1984 Big Twin engine, a solid set of piston rings is crucial for proper compression and oil control. This set from S&S Cycle is designed to help you get your engine back to performing its best.

These rings feature a moly face coating. Molybdenum compounds are known for improving wear resistance, which means they can handle more miles and heat before needing replacement. This coating also helps with heat tolerance and ensures a good seal between the piston and cylinder wall, which is key for making good power and preventing oil from getting into the combustion chamber.

This set is specifically sized at .090 inches oversize, so make sure your cylinders have been bored to match this dimension. Remember, this part is not CARB approved and cannot be shipped to California.
