Cometic Top End Gasket Kit for 4-Stroke Engines

Ensure peak performance and reliable sealing for your 4-stroke engine with the premium Cometic Top End Gasket Kit. Engineered for today's highest-output motorcycles, this kit provides everything needed for a complete top-end rebuild, guaranteeing a perfect fit and exceptional durability.

Description

The Cometic Top End Gasket Kit is meticulously designed to meet the rigorous demands of high-horsepower, high-cylinder-pressure engines. Featuring advanced Multi-Layered Steel (MLS) head gaskets, this kit promotes an even torque load across the sealing surface, significantly reducing bore distortion and improving piston ring seal for enhanced power output. These MLS head gaskets are constructed with outer layers embossed and coated with a durable Viton® rubber, ensuring superior sealing under extreme conditions. With a bore size of 87.50 mm (3.444") and a thickness of 1.09 mm (0.043"), this kit is precision-engineered for a perfect fit.

Utilizing Cometic's Extreme Sealing Technology (EST), the kit includes embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material. This innovative gasket material effectively draws heat away from the combustion ring, dissipating it evenly across the gasket surface. This crucial feature eliminates hot spots, preventing premature gasket failure and maintaining optimal engine temperatures. Proudly made in the USA, the Cometic Hi-Performance Top End Gasket Kit offers unparalleled quality and reliability for your motorcycle's 4-stroke engine.
