Cometic Top End Gasket Kit for 4-Stroke Engines

Ensure peak performance and superior sealing for your 4-stroke engine with the Cometic Top End Gasket Kit. This comprehensive kit provides all essential gaskets and O-rings required for a complete top-end rebuild or refresh, engineered for the demands of high-output machines.

Description

The Cometic 4-Stroke Top End Gasket Kit is meticulously engineered to deliver exceptional durability and sealing integrity for today's most powerful motorcycle engines. Utilizing advanced Multi-Layer Steel (MLS) head gaskets, this kit promotes an even torque load across the sealing surface, significantly reducing bore distortion and enhancing piston ring seal for increased power output. These high-performance MLS head gaskets are specifically designed for 4-stroke naturally aspirated and boosted machines, featuring an embossed design with a Viton® rubber coating on the outer layers to withstand extreme cylinder pressures and temperatures. The innovative EST (Extreme Sealing Technology) further reinforces this commitment to reliability, incorporating embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material. This specialized gasket material efficiently draws heat away from the combustion ring, distributing it evenly across the gasket surface to prevent hot spots and premature gasket failure. Made in the USA, this Cometic Hi-Performance gasket kit, with a 94.00 mm (3.700") bore size and 0.69 mm (0.027") thickness, guarantees a precise fit and long-lasting sealing for your critical engine components.
