About this part

Product Details

S&S Cycle is well-known for making performance engine parts for Harley-Davidson motorcycles. This piston ring set is built for their XL models with 4-inch bore engines, specifically those from 1986 through 2003. These rings are a crucial part of your engine's top end, responsible for sealing the combustion chamber and controlling oil flow down the cylinder walls.

What sets these rings apart is the 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 more efficient power delivery from your engine. Because they improve wear resistance and heat tolerance, they're a solid choice for rebuilding or upgrading your XL engine.
