Top End Gasket Kit - 85 mm - Polaris 400

The Cometic C7265 Top End Gasket Kit is designed specifically for Polaris 400 models with an 85mm bore, ensuring a precise fit and reliable performance. This kit includes a high-quality MLS head gasket, base gasket, and cylinder O-rings, along with other essential seals for a comprehensive top end rebuild. The MLS head gasket features a multi-layered steel construction with embossed outer layers coated with Viton rubber, promoting even torque distribution and reducing bore distortion for enhanced sealing and power output. These gaskets are engineered to withstand high-cylinder pressures and temperatures typical of high-performance 4-stroke engines, whether naturally aspirated or boosted. The EST (Extreme Sealing Technology) gaskets incorporate embossed stainless steel components covered with a proprietary rubber material that helps dissipate heat efficiently, preventing hot spots and gasket failure. This makes the kit ideal for high-horsepower applications and demanding riding conditions, providing a durable, sealed interface between the cylinder head and engine block. Suitable for Polaris 400 models from the late 1980s and early 1990s, this gasket kit is manufactured in the USA to meet high standards of quality and performance. Proper installation ensures optimal compression, power, and longevity of your engine, making this kit an essential upgrade or rebuild component for enthusiasts and professionals alike.
