About this part

Product Details

S&S Cycle is well-known for making performance engine parts for Harley-Davidson motorcycles. This set of piston rings is built for 1999-2017 Big Twin models and features a chromoly face for improved durability.

These rings are designed for a 3.927-inch bore, which is a standard size for many Big Twin engines. A good set of piston rings is crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. This set is a solid option if you're rebuilding or refreshing the top end of your engine.
