Cometic Hi-Performance 4-Stroke Top End Gasket Kit

Maximize your engine's potential with the Cometic Hi-Performance 4-Stroke Top End Gasket Kit, engineered for today's most demanding machines. This comprehensive kit provides all the essential gaskets and O-rings needed for a complete top end rebuild, ensuring optimal sealing and reliability.

Description

Designed specifically for 4-stroke engines, the Cometic Hi-Performance Top End Gasket Kit delivers unparalleled sealing capabilities for both naturally aspirated and boosted applications. At its core are advanced Multi-Layer Steel (MLS) head gaskets, meticulously crafted to promote an even torque load across the sealing surface. This innovative design significantly reduces bore distortion, leading to a superior piston ring seal and ultimately, more power output from your engine. With a precise bore size of 95.00 mm (3.750") and a slim thickness of 0.58 mm (0.023"), these gaskets are engineered for exact fitment and performance. The outer layers of the MLS head gaskets are embossed and coated with a durable Viton rubber, allowing them to withstand the extreme cylinder pressures and high temperatures of modern, high-horsepower engines. The kit also features Cometic's proprietary EST (Extreme Sealing Technology) which includes embossed stainless steel head, base, and rocker gaskets, all covered with a specialized rubber material. This material efficiently draws heat away from the combustion ring, distributing it evenly across the gasket surface to prevent hot spots and premature gasket failure, ensuring long-lasting performance. Proudly Made in the USA, this gasket kit provides the professional-grade components you need for a reliable and powerful top end rebuild.
