Cometic Hi-Performance Top End Gasket Kit

Ensure peak engine performance and reliability with the Cometic Hi-Performance Top End Gasket Kit. This comprehensive kit provides all the essential gaskets and seals required for a complete top end overhaul on your 4-stroke motorcycle, engineered for today's demanding high-output engines.

Description

Designed for optimal sealing in high-performance 4-stroke engines, this Cometic Top End Gasket Kit utilizes advanced Multi-Layer Steel (MLS) head gaskets. These innovative gaskets are crucial for promoting an even torque load across the sealing surface, which significantly reduces bore distortion and enhances piston ring seal for increased power output. Engineered to excel in both naturally aspirated and boosted machines, the MLS head gaskets feature a robust multi-layered steel design with embossed outer layers coated in Viton rubber. This construction allows them to withstand the extreme demands of high-horsepower and high-cylinder-pressure environments, ensuring long-lasting durability and preventing gasket failure.

The kit also incorporates Cometic's Extreme Sealing Technology (EST), which includes embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material. This specialized material is engineered to draw heat away from the combustion ring, dissipating it evenly across the gasket surface. This critical feature eliminates hot spots, a common cause of gasket failure, thereby extending engine life and maintaining consistent performance. With a bore size of 84.00 mm (3.307") and a thickness of 0.69 mm (0.027"), this gasket kit is precision-made in the USA to meet the highest quality standards for your motorcycle's engine maintenance and upgrade needs.
