What is Included

This listing is for a Yamaha OEM standard-size piston ring kit. Piston rings are sized for one piston. Verify the quantity required for your complete engine rebuild before ordering.

What Piston Rings Do

Piston rings seal the space between the piston and cylinder wall while allowing the piston to move freely through the cylinder.

The ring package helps contain combustion pressure, control engine oil on the cylinder wall and transfer heat from the piston into the cylinder.

Standard Rings or Oversize Rings?

Check Ring End Gap During Assembly

Piston ring end gap should be checked in the cylinder during engine assembly. Ring specifications can vary based on piston manufacturer, bore size and engine application.

Follow the Yamaha, Mercury, Wiseco or Vertex specifications applicable to the piston and engine being assembled.
