About this product
Ensure peak engine performance and reliability with the Cometic Hi-Performance Top End Gasket Kit. This comprehensive kit provides all necessary components for a complete top end rebuild on your 4-stroke engine, engineered to meet the rigorous demands of today's highest-output machines.
Description
Designed for motorcycle enthusiasts and professionals, this Cometic gasket kit is built with advanced Multi-Layer Steel (MLS) head gaskets. This cutting-edge material promotes an even torque load across the sealing surface, significantly reducing bore distortion and improving piston ring seal for enhanced power output. The MLS head gaskets are specifically crafted for high-horsepower, high-cylinder-pressure 4-stroke engines, whether naturally aspirated or boosted. They feature a sophisticated design with embossed outer layers coated in Viton rubber, ensuring exceptional durability and sealing integrity under extreme conditions. The kit also incorporates Cometic's Extreme Sealing Technology (EST), utilizing embossed stainless steel for the head, base, and rocker gaskets, all covered with a proprietary rubber material. This innovative gasket material actively draws heat away from the combustion ring, dissipating it evenly to eliminate hot spots and prevent premature gasket failure. With a bore size of 98.00 mm (3.858") and a thickness of 0.69 mm (0.027"), this kit provides a precise fit and superior sealing for your high-performance engine. Proudly made in the USA, this Cometic Hi-Performance Gasket Kit offers unmatched quality and peace of mind for your engine's top end.
