Cometic EST Hi-Performance 4-Stroke Top End Gasket Kit

Elevate your engine's performance and reliability with the Cometic EST Hi-Performance 4-Stroke Top End Gasket Kit. Engineered for demanding motorcycle applications, this comprehensive kit provides all the essential components for a flawless top-end rebuild, ensuring optimal sealing and power delivery for your high-output machine.

Description

Designed to meet the rigorous demands of today's most powerful 4-stroke naturally aspirated and boosted engines, the Cometic EST Top End Gasket Kit is a testament to precision engineering. 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. These robust head gaskets are coated with a durable Viton rubber on their outer layers, providing exceptional resilience against extreme temperatures and pressures. The kit leverages Cometic's proprietary Extreme Sealing Technology (EST), incorporating embossed stainless steel head, base, and rocker gaskets that are covered with a specialized rubber material. This ensures an unparalleled seal, critical for high-cylinder-pressure environments. Furthermore, the specialized gasket material actively draws heat away from the combustion ring, dissipating it evenly across the gasket surface to eliminate hot spots and prevent premature gasket failure. With a precise bore size of 93.50 mm (3.681") and a thickness of 0.46 mm (0.018"), this Cometic 4-Stroke Top End Gasket Kit delivers exact fitment and uncompromising quality, proudly made in the USA.
