Description

Polaris 800 engines rely on a properly sealed and matched top end to hold compression and make consistent power. This complete top end rebuild kit is designed for rebuilds where wear or damage makes partial repairs a risk. Every component in this kit is backed by a 1-year REV6 parts warranty.

By replacing the cylinder, pistons, and gaskets together, you eliminate uneven wear and sealing issues. As a result, compression stabilizes, break-in improves, and the engine runs cleaner after reassembly.

THIS KIT INCLUDES

• New cylinder
• Top end gasket set
• Moly upgraded pistons
