About this part

Product Details

If you're rebuilding the top end of your 1984 and later Big Twin motorcycle, a good set of piston rings is crucial for proper engine function. These S&S Cycle rings are designed to fit 4-1/8 inch bore engines and are the standard size, meaning they're meant for cylinders that haven't been bored out.

What sets these rings apart is their moly facing. This is a molybdenum compound coating that helps them wear better over time, handle more heat without issues, and create a tighter seal against the cylinder wall. A good seal means better compression and less oil getting past the rings into the combustion chamber, which is key for performance and longevity.

Keep in mind these rings are not CARB approved, so they cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
