It is used on Chrysler inboard exhaust manifold setups and installs with exhaust risers 18-1939, 18-1999, and 18-1907, making it a direct match for boats already running one of those risers. The kit includes the 18-0476-1 elbow gasket, the blocked-style gasket required for closed cooling systems, so the elbow-to-riser joint seals correctly without introducing raw water into a closed loop. Choosing the correct gasket type matters: an open-gasket kit is intended for open (raw water) cooling systems, while this 18-8535 kit's blocked gasket is specifically for closed systems, so installers should confirm their cooling configuration before ordering. The kit is compact and lightweight, finished in white, and is sized to drop into the existing elbow mounting hardware on compatible risers. It is sold as a complete small-parts kit rather than an individual gasket, so the correct blocked elbow gasket is on hand at install time instead of being sourced separately.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-8535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Exhaust Elbow Mounting Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Type:\u003c\/strong\u003e Blocked (for closed cooling system)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Gasket:\u003c\/strong\u003e 18-0476-1 Elbow Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Risers:\u003c\/strong\u003e 18-1939, 18-1999, 18-1907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Chrysler Inboard Exhaust Manifolds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282127275\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUsed with exhaust risers 18-1939, 18-1999, and 18-1907\u003c\/li\u003e\n\u003cli\u003eFor Chrysler inboard exhaust manifolds with a closed cooling system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eNo OEM cross-reference numbers are listed for this part number.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-8535 Exhaust Elbow Mounting Kit?\u003c\/strong\u003e The 18-8535 kit includes the 18-0476-1 blocked elbow gasket, which is the gasket needed for a closed cooling system installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich exhaust risers is the 18-8535 mounting kit compatible with?\u003c\/strong\u003e This kit is used with exhaust risers 18-1939, 18-1999, and 18-1907.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-8535 kit for an open or closed cooling system?\u003c\/strong\u003e It is for a closed cooling system, since it includes the 18-0476-1 blocked-style elbow gasket rather than an open gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the 18-8535 kit and an open-gasket mounting kit?\u003c\/strong\u003e The 18-8535 kit uses the blocked 18-0476-1 elbow gasket for closed cooling systems, while an open-gasket kit uses a different gasket for open (raw water) cooling systems and is a separate part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engine application is the 18-8535 mounting kit designed for?\u003c\/strong\u003e It is designed for Chrysler inboard exhaust manifold setups that use one of the 18-1939, 18-1999, or 18-1907 risers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-8535 Exhaust Elbow Mounting Kit?\u003c\/strong\u003e The kit is finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-8535 Exhaust Elbow Mounting Kit weigh?\u003c\/strong\u003e It weighs 0.24 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-8535 kit?\u003c\/strong\u003e The kit measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-8535 kit come with mounting hardware or just the gasket?\u003c\/strong\u003e The 18-8535 is sold as a mounting kit built around the 18-0476-1 elbow gasket, rather than as a standalone gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-8535 Exhaust Elbow Mounting Kit?\u003c\/strong\u003e The UPC is 808282127275.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre there OEM cross-reference numbers for the 18-8535 kit?\u003c\/strong\u003e No OEM cross-reference numbers are listed for part number 18-8535.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-8535 kit be used with any exhaust riser?\u003c\/strong\u003e No, it is intended for use with risers 18-1939, 18-1999, and 18-1907 specifically.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988434137307,"sku":"SIE-18-8535","price":14.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-8535_lg__69437.1558131794.500.750.jpg?v=1785188403","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-8535-exhaust-elbow-mounting-kit-for-marine-inboard-exhaust-manifolds","provider":"Good Vibes Marina","version":"1.0","type":"link"}
