Designed specifically for demanding 4-stroke applications, this kit ensures optimal sealing and durability, crucial for maintaining peak power output and extending engine life.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Cometic Hi-Performance Top End Gasket Kit is engineered for today's most powerful naturally aspirated and boosted 4-stroke engines. Central to its superior design are the Multi-Layer Steel (MLS) head gaskets, which are crucial for achieving an even torque load across the entire gasket sealing surface. This innovative design significantly reduces bore distortion, leading to a better piston ring seal and ultimately, more power and efficiency from your engine.\u003c\/p\u003e\n\u003cp\u003eEach 4-stroke head gasket is crafted with a multi-layered steel construction, featuring outer layers that are embossed and coated with a high-durability Viton rubber. This robust material combination allows these head gaskets to meet and exceed the rigorous demands of modern high-horsepower, high-cylinder-pressure engines. The kit also incorporates Cometic's Extreme Sealing Technology (EST), utilizing embossed stainless steel for the head, base, and rocker gaskets, all covered with a proprietary rubber material for an uncompromising seal.\u003c\/p\u003e\n\u003cp\u003eBeyond strength, the advanced gasket material effectively draws heat away from the combustion ring, dissipating it evenly across the gasket surface. This critical feature eliminates dangerous hot spots and prevents premature gasket failure, ensuring consistent engine performance. With a precise bore size of 77.00 mm (3.032\") and a thickness of 0.69 mm (0.027\"), this kit provides the exact fitment needed for your top end rebuild. Proudly made in the USA, this kit includes all the correct base, head gasket, cylinder O-rings, and other top end specific O-rings or seals necessary for a complete and reliable top end removal and replacement (R\u0026amp;R).\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAdvanced MLS Head Gaskets:\u003c\/strong\u003e Utilizes Multi-Layer Steel (MLS) technology to ensure even torque distribution, reduce bore distortion, and enhance piston ring seal for increased 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 coated with a proprietary rubber material for an unyielding seal under extreme conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh-Performance 4-Stroke Design:\u003c\/strong\u003e Engineered specifically for high-output, naturally aspirated, and boosted 4-stroke engines, handling high horsepower and cylinder pressures with ease.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eViton Rubber Coating:\u003c\/strong\u003e Outer layers of the head gaskets are embossed and coated with durable Viton rubber, providing exceptional resistance to heat and chemicals for long-lasting reliability.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSuperior Heat Management:\u003c\/strong\u003e Gasket material efficiently dissipates heat away from the combustion ring, preventing hot spots and significantly reducing the risk of gasket failure.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComprehensive Kit for R\u0026amp;R:\u003c\/strong\u003e Includes all necessary base, head gasket, cylinder O-rings, and other top end specific seals required for a complete and confident top end rebuild.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Guarantees high-quality manufacturing and materials, ensuring a reliable and durable product.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Top End\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Hi-Performance\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUnits:\u003c\/strong\u003e Kit\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e MLS (Multi-layer Steel)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBore Size:\u003c\/strong\u003e 77.00 mm (3.032\")\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 0.69 mm (0.027\")\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4-Stroke\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVendor Part Number:\u003c\/strong\u003e C3549-EST\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cometic","offers":[{"title":"Default Title","offer_id":62392715280714,"sku":"09347842","price":718.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/479464d8945c976591bab476662ffcbb.webp?v=1781799494","url":"https:\/\/partsdenmark.se\/products\/cometic-hi-performance-top-end-gasket-kit-for-4-stroke-3","provider":"Parts Denmark","version":"1.0","type":"link"}
