What does 'Moly Faced' mean for these piston rings?

Moly faced means the rings have a coating made of molybdenum. This coating is known to improve wear resistance, help the rings tolerate higher temperatures, and create a better seal against the cylinder wall.

What does the '.020in' size indicate?

The '.020in' indicates that these rings are 0.020 inches larger than the standard size. This is used when the cylinder bore has been slightly enlarged, often during an engine rebuild or to correct wear.

Are these rings CARB approved?

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

About this part

Product Details

This is a Moly Faced piston ring set from S&S Cycle, sized for Big Twin engines with a 3-7/16 inch bore and a .020 inch oversize. These rings are coated with a molybdenum compound, which helps them resist wear better and handle higher temperatures. This coating also contributes to improved sealing within the cylinder, helping your engine run more efficiently.

When you're rebuilding the top end of your engine, getting the right piston rings is crucial for proper compression and oil control. The moly facing on these rings is a practical choice for improved durability and performance over standard rings. They are designed to fit right into the groove on your pistons for a straightforward installation during your engine build.
