Product Details
If you're rebuilding the top end of your 1999 and newer Big Twin engine, a good set of piston rings is crucial for proper sealing and performance. These Moly Faced rings from S&S Cycle are designed to help your engine run smoothly and efficiently.
The molybdenum compound coating on these rings is a notable feature. It helps them resist wear and handle heat better than standard rings, which means they'll maintain a good seal against the cylinder wall for longer. This improved sealing helps keep combustion pressure where it belongs and prevents oil from getting into the combustion chamber, contributing to better overall engine health and performance.
This set is specifically sized at .020 inch undersize, which is important to match with your piston and cylinder bore dimensions during your rebuild. Remember that these rings are not CARB approved and cannot be shipped to California.
