This is a Wiseco 103.429mm (4.072 inch) piston ring set, designed for a single cylinder. You get the rings needed to properly seal one piston, which is crucial for engine performance. Wiseco develops these rings to work specifically with their pistons, ensuring a good seal that helps control oil and provides compression. They are tested for race-ready performance, meaning they are built to handle demanding conditions.

Properly functioning piston rings are essential for the overall health of your engine. They are responsible for creating a seal between the piston and the cylinder wall, which prevents combustion gases from escaping into the crankcase and stops oil from entering the combustion chamber. This set is made to Wiseco's specifications to achieve optimal sealing and performance.
