Cometic Hi-Performance 4-Stroke Gasket Kit

Ensure peak engine performance and reliable sealing with the Cometic 4-stroke top end gasket kit. This comprehensive kit provides all necessary components for a complete top-end rebuild, designed to meet the rigorous demands of high-output motorcycle engines.

Description

The Cometic Hi-Performance 4-Stroke Gasket Kit is engineered for superior sealing and durability, making it an essential upgrade for any serious rider or mechanic. This advanced high-performance gasket kit features Multi-Layer Steel (MLS) head gaskets, a cornerstone of modern engine sealing technology. The MLS design promotes an even torque load across the gasket surface, significantly reducing bore distortion and enhancing piston ring seal for increased power and efficiency. Each 4-stroke head gasket is crafted to perform flawlessly in today’s highest-output naturally aspirated and boosted machines, utilizing a multi-layered steel construction with outer layers embossed and coated with a Viton® rubber coating, ensuring resilience against extreme temperatures and pressures.

Cometic's Extreme Sealing Technology (EST) is at the heart of this motorcycle engine seal kit. The kit includes embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material that delivers an uncompromised seal. This specialized head gasket material efficiently draws heat away from the combustion ring, dissipating it evenly across the gasket surface. This crucial feature eliminates dangerous hot spots and prevents premature gasket failure, extending engine life and maintaining consistent performance. With a precise bore size of 96.00 mm (3.779") and a thickness of 0.58 mm (0.023"), this kit provides the exact fitment and sealing integrity required for demanding applications. Proudly made in the USA, the Cometic C3621 kit ensures you’re installing a product of the highest quality and reliability.
