What does the Moly Faced coating do?

The Moly Faced coating is a molybdenum compound applied to the piston rings. This coating is known for improving wear resistance, helping the rings tolerate higher temperatures, and creating a better seal within the cylinder.

What does '.010in' mean for these piston rings?

The '.010in' designation means these piston rings are 0.010 inches smaller than the standard size. This is an undersize measurement, typically used when the cylinder bore has been honed or machined to a slightly larger diameter 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.

About this part

Product Details

This S&S Cycle piston ring set includes the rings you need to rebuild your engine. Specifically, you get a set of Moly Faced piston rings, sized .010 inch undersize for your 1999 and newer Big Twin (BT) engine. These rings are coated with a molybdenum compound, which is a well-known material for improving wear resistance, handling higher heat, and creating a better seal between the piston and cylinder wall.

The molybdenum coating on these rings helps them stand up better to the rigors of engine operation. This means they can handle more heat and resist wear over time, contributing to a longer-lasting engine rebuild. A good seal is crucial for performance and efficiency, and these rings are designed to help achieve that.
