Cometic EST Top End Gasket Kit - C3459-EST

Ensure peak engine performance and reliability with the Cometic Hi-Performance Top End Gasket Kit. Designed for demanding 4-stroke engines, this comprehensive kit provides all the necessary gaskets and seals for a complete top end rebuild, offering superior sealing and durability for your motorcycle.

Description

Engineered for today's highest-output 4-stroke naturally aspirated and and boosted machines, the Cometic Hi-Performance Top End Gasket Kit delivers unmatched sealing integrity. At its core are advanced MLS (Multi-layer Steel) head gaskets, meticulously designed to promote an even torque load across the sealing surface. This innovative construction significantly reduces bore distortion, leading to an improved piston ring seal and ultimately, more power for your engine. The outer layers of these MLS gaskets are embossed and coated with a Viton rubber material, making them exceptionally resilient to the high cylinder pressures and temperatures found in modern performance engines.

This kit utilizes Cometic's renowned EST (Extreme Sealing Technology), which includes embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material. This specialized head gasket material actively draws heat away from the combustion ring, distributing it evenly across the gasket surface. This crucial feature eliminates hot spots and prevents premature gasket failure, ensuring long-term reliability. With a precise bore size of 92.00 mm (3.622") and a thickness of 0.46 mm (0.018"), this kit is built to exact specifications for a perfect fit and optimal sealing. Proudly made in the USA, Cometic stands for quality and performance.
