Cometic Top End Gasket Kit for 4-Stroke Engines

Ensure peak engine performance and sealing integrity for your high-output motorcycle with the Cometic 4-Stroke Top End Gasket Kit. Engineered for demanding environments, this comprehensive kit provides all the essential components for a complete top-end rebuild or refresh.

Description

The Cometic Hi-Performance Top End Gasket Kit is meticulously designed to meet the rigorous demands of today's advanced 4-stroke engines. Featuring state-of-the-art Multi-Layer Steel (MLS) head gaskets, this kit ensures an even torque load across the sealing surface, significantly reducing bore distortion and enhancing piston ring seal for improved power output. These premium head gaskets are crafted to excel in both naturally aspirated and boosted machines, utilizing a robust multi-layered steel design. The outer layers are embossed and coated with a durable Viton rubber, specifically engineered to withstand high-horsepower and extreme cylinder pressure conditions. The kit also incorporates Cometic's innovative EST (Extreme Sealing Technology), including embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material. This advanced gasket material efficiently draws heat away from the combustion ring, dissipating it evenly across the gasket surface to prevent hot spots and premature gasket failure. Precision-engineered for a 90.00 mm (3.543") bore size and a thickness of 1.09 mm (0.043"), this Cometic gasket kit is made in the USA, guaranteeing exceptional quality and reliability for your motorcycle top end gasket set.
