Cometic Hi-Performance Top End Gasket Kit

Ensure peak engine performance and reliability for your 4-stroke motorcycle with the Cometic Hi-Performance Top End Gasket Kit. This comprehensive kit provides all necessary gaskets and seals for a complete top end overhaul, designed for the demands of modern high-output engines.

Description

The Cometic Hi-Performance Top End Gasket Kit is engineered to deliver superior sealing and durability for your motorcycle's 4-stroke engine. Central to its design are the advanced Multi-Layer Steel (MLS) head gaskets, which promote an even torque load across the sealing surface. This innovative construction significantly reduces bore distortion, leading to a better piston ring seal and ultimately, more power and efficiency from your engine. These 4-stroke head gaskets are specifically crafted to perform exceptionally well on today’s highest-output naturally aspirated and boosted machines, handling high-horsepower and extreme cylinder pressures with ease. The MLS design features embossed outer layers coated with a resilient Viton rubber, ensuring a robust and long-lasting seal.

Further enhancing its capabilities, the kit incorporates Cometic's Extreme Sealing Technology (EST) with embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material. This specialized head gasket material efficiently draws heat away from the combustion ring, dissipating it evenly across the gasket surface to prevent detrimental hot spots and premature gasket failure. With a bore size of 79.00 mm (3.110") and a thickness of 0.69 mm (0.027"), this kit provides a precise fit for optimal engine rebuilds. Proudly made in the USA, this Cometic top end gasket kit is an essential component for any serious motorcycle engine rebuild or performance upgrade.
