Description

Polaris 800 engines rely on a properly sealed top end to maintain compression and consistent power. This top end rebuild kit is designed for engines that need piston and gasket replacement without a full overhaul. Every component in this kit is backed by a 1-year REV6 parts warranty.

By replacing pistons and top end gaskets together, you restore sealing and avoid uneven wear during break-in. As a result, compression improves and the engine runs cleaner after reassembly.

THIS KIT INCLUDES

• Top end gasket set
• Moly upgraded pistons
