About this part

Product Details

This is a 4.320 inch bore piston ring set from S&S Cycle, specifically made for 2017 and newer M8 engine models. If you're rebuilding the top end of your M8 engine, new rings are a critical part of ensuring proper seal and compression. These rings are designed to fit the specific bore size of your M8 pistons, helping to restore lost performance and oil control.

S&S Cycle is known for making well-built engine components, and this ring set is no exception. They are designed to provide a solid seal between the piston and cylinder wall, which is essential for efficient combustion and preventing oil from entering the combustion chamber. Proper ring seal means you get the most power out of your engine and keep oil consumption in check.

This set includes the necessary rings for one piston. When working on your M8 engine, always refer to the manufacturer's service manual for the correct installation procedures and specifications.
