What does a piston ring set do?

Piston rings create a seal between the piston and the cylinder wall. This seal prevents combustion gases from escaping into the crankcase and stops oil from entering the combustion chamber, which is vital for engine performance and efficiency.

How many cylinders does this set cover?

This 2-pack set includes enough piston rings to service two cylinders, which is suitable for V-twin engines like the M8.

Can this part be shipped to California?

No, this piston ring set is not CARB approved and cannot be shipped to California due to emissions regulations.

About this part

Product Details

If you're rebuilding the top end of your 2017 or newer M8 engine, a fresh set of piston rings is a critical component. These S&S Cycle piston rings are designed to fit the specific 4.320-inch bore of your M8 motor, ensuring a proper seal between the piston and cylinder wall. A good seal is what keeps combustion pressure where it belongs and oil out of the combustion chamber, which is key for performance and engine longevity.

This set comes with enough rings for two cylinders, making it convenient for a V-twin engine. S&S Cycle is well-known in the performance motorcycle world, and these rings are built to meet the demands of their engines. Proper installation is important here; making sure the rings are seated correctly in the piston grooves and oriented properly is what allows them to do their job effectively.
