This standard bore piston kit is a direct replacement that requires no cylinder boring—only a light hone to break the glaze for proper ring seating. The piston is manufactured from high-quality materials designed to meet factory specifications for reliable performance and long service life. WSM offers this kit as a cost-effective alternative to OEM parts while maintaining the same quality standards.

Note: Three piston kits are required to rebuild one complete three-cylinder Polaris 780 motor. If cylinders show damage or excessive wear beyond factory specifications, boring to an oversize dimension may be necessary.
