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.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\nDesigned 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 \u003cstrong\u003eCometic 4-Stroke Top End Gasket Kit\u003c\/strong\u003e delivers exact fitment and uncompromising quality, proudly made in the USA.\n\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComplete Top End Rebuild Solution:\u003c\/strong\u003e Includes all correct base, head, and cylinder O-rings, plus other top-end specific O-rings and seals required for a thorough top-end overhaul.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAdvanced Multi-Layer Steel (MLS) Head Gaskets:\u003c\/strong\u003e Utilizes a state-of-the-art MLS design with Viton rubber coating for even torque load, reduced bore distortion, and enhanced piston ring seal, maximizing engine power.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExtreme Sealing Technology (EST):\u003c\/strong\u003e Features embossed stainless steel head, base, and rocker gaskets with a proprietary rubber material, providing superior sealing integrity for high-horsepower, high-cylinder-pressure engines.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptimized Heat Dissipation:\u003c\/strong\u003e Specially formulated gasket material efficiently draws heat away from the combustion ring, preventing hot spots and ensuring long-term gasket reliability and performance.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEngineered for High-Output 4-Stroke Engines:\u003c\/strong\u003e Specifically designed to perform flawlessly in today’s highest-output 4-stroke naturally aspirated and boosted machines.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProudly Made in the USA:\u003c\/strong\u003e Guarantees exceptional quality, precision, and durability, adhering to the highest manufacturing standards.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eType: Top End Gasket Kit\u003c\/li\u003e\n    \u003cli\u003eModel: Hi-Performance EST\u003c\/li\u003e\n    \u003cli\u003eUnits: Kit\u003c\/li\u003e\n    \u003cli\u003eMaterial: MLS (Multi-layer Steel)\u003c\/li\u003e\n    \u003cli\u003eBore Size: 93.50 mm (3.681\")\u003c\/li\u003e\n    \u003cli\u003eThickness: 0.46 mm (0.018\")\u003c\/li\u003e\n    \u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n    \u003cli\u003eVendor Part Number: C3446-EST\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cometic","offers":[{"title":"Default Title","offer_id":62385009393994,"sku":"09344166","price":84.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/c05fcc86578080f46fbda3db4dbfa645.webp?v=1781771568","url":"https:\/\/partsdenmark.de\/products\/cometic-est-hi-performance-4-stroke-top-end-gasket-kit","provider":"Parts Denmark","version":"1.0","type":"link"}
