Product Details
These S&S Cycle piston rings are .020 inch oversized, meaning they are designed to fit cylinders that have been bored out by 0.020 inches. This size is common when rebuilding an engine that has seen some wear and needs a fresh bore to bring it back to spec. They are made for 1984 and newer Big Twin Harley-Davidson style engines.
When you're rebuilding the top end of your engine, getting the right piston ring size is crucial for a good seal. These rings from S&S Cycle are a well-built option for that job. They are sold as a 2-pack, which is typically what you'd need for a V-twin engine.
Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your service manual for proper installation procedures and ring gap specifications.
