Top End Gasket Kit - 85 mm - Polaris 400

The COMETIC Top End Gasket Kit (Part C7265) is designed for high-performance Polaris 400 engines, offering reliable sealing and durability for your rebuild or repair. This comprehensive kit includes a precision-machined base gasket, MLS head gasket, and cylinder O-rings, ensuring all top-end components are properly sealed. The gasket materials are engineered to withstand high cylinder pressures and temperatures typical of today’s high-output 4-stroke engines, whether naturally aspirated or boosted. The multi-layered steel design features embossed outer layers coated with Viton rubber, providing excellent heat resistance, sealing integrity, and resistance to hot spots that can lead to gasket failure. These materials help dissipate heat evenly across the gasket surface, promoting longer engine life and consistent performance. The kit also includes other essential O-rings and seals needed for a complete top-end rebuild, ensuring compatibility and proper fitment. Made in the USA, the COMETIC C7265 gasket kit incorporates Extreme Sealing Technology (EST), which enhances sealing performance under demanding conditions. The embossed stainless steel components, combined with proprietary rubber coatings, optimize gasket resilience and sealing efficiency. Whether you're restoring a high-horsepower engine or performing routine maintenance, this gasket kit provides the quality and reliability needed for peak engine performance and long-term durability.
