94-2216X 3-1/2" bore piston ring set. Std

These standard 3-1/2 inch bore piston rings from S&S Cycle are manufactured from chromoly to provide a superior seal and excellent wear resistance. Sold as a pair, these rings are designed as direct replacements for stock S&S Evolution style pistons, ensuring optimal compression and oil control within the cylinder. S&S is a leader in V-twin performance, and these rings are engineered to withstand the rigours of high-heat environments common in air-cooled Harley-Davidson engines. Utilizing chromoly construction helps reduce friction while maintaining a consistent tension against the cylinder wall for improved engine efficiency and longevity.
