Cometic Top End Gasket Kit for Hi-Performance Engines

Ensure a reliable and powerful engine rebuild with the Cometic Top End Gasket Kit. Designed for high-performance applications, this comprehensive kit provides all the essential sealing components needed to restore your motorcycle's top end with precision and durability, delivering optimal power and longevity.

Description

The Cometic Top End Gasket Kit is engineered for today's most demanding engines, ensuring superior sealing and an even torque load across critical surfaces. This kit includes the correct base gasket, head gasket, and cylinder O-rings, along with other top-end specific O-rings and seals required for the removal and reinstallation (R&R) of your top end. Featuring advanced Multi-Layer Steel (MLS) head gaskets, this kit minimizes bore distortion and enhances piston ring seal, directly contributing to increased power output. These high-output head gaskets are specifically designed for 4-stroke naturally aspirated and boosted machines, utilizing a robust multi-layered steel construction with embossed outer layers coated in Viton rubber, making them ideal for high-horsepower, high-cylinder-pressure environments.

Further enhancing its sealing capabilities, the kit incorporates EST (Extreme Sealing Technology), which includes embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material. This advanced material effectively draws heat away from the combustion ring, dissipating it evenly across the gasket surface to prevent hot spots and premature gasket failure. With a precise bore size of 71.00 mm and a thickness of 0.51 mm (0.020"), this Cometic kit provides the exact fitment required for optimal engine performance. Proudly Made in the USA, this gasket kit represents the pinnacle of quality and engineering for serious motorcycle enthusiasts and professionals.
