It is designed for use with Crusader exhaust manifolds 18-1929 (Starboard) and 18-1933 (Port), forming the seal that keeps exhaust gases and cooling water properly contained at the manifold-to-elbow joint. This gasket is also included as a component of the 18-8515 mounting kit, so buyers assembling or servicing that kit already have this gasket on hand and do not need to order it separately unless replacing a worn unit individually.\u003c\/p\u003e\u003cp\u003eKeeping this gasket in good condition is important for preventing exhaust leaks and water intrusion at the manifold connection, both of which can lead to reduced engine performance, corrosion, or more serious cooling system issues if left unaddressed. At just 0.02 pounds, it is a lightweight, low-cost component that is inexpensive insurance against a failed seal during routine exhaust system maintenance or manifold replacement.\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 18-0305-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Exhaust Elbow Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282365738\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Crusader Exhaust Manifolds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Reference \/ OEM Number:\u003c\/strong\u003e 96108\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUsed with Crusader Exhaust Manifold 18-1929 (Starboard)\u003c\/li\u003e\n\u003cli\u003eUsed with Crusader Exhaust Manifold 18-1933 (Port)\u003c\/li\u003e\n\u003cli\u003eIncluded in Mounting Kit 18-8515\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e96108\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is Sierra part 18-0305-1 used for?\u003c\/strong\u003e It is the elbow gasket that seals the joint between the exhaust manifold and the exhaust elbow, used with Crusader exhaust manifolds 18-1929 and 18-1933.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this gasket fit both the port and starboard manifolds?\u003c\/strong\u003e Yes, gasket 18-0305-1 is used with both the starboard manifold 18-1929 and the port manifold 18-1933.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-0305-1 the same gasket included in the 18-8515 mounting kit?\u003c\/strong\u003e Yes, this exact gasket, 18-0305-1, is included as a component of the 18-8515 mounting kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM number does this gasket cross-reference to?\u003c\/strong\u003e Sierra 18-0305-1 corresponds to OEM number 96108.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this gasket weigh?\u003c\/strong\u003e The 18-0305-1 exhaust elbow gasket weighs 0.02 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-0305-1 gasket made of?\u003c\/strong\u003e The dossier does not specify the gasket material for 18-0305-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need a different gasket for the elbow with the 4 inch outlet?\u003c\/strong\u003e Yes, the elbow with a 4 inch outlet (18-1928) uses a different gasket, 18-0309-1, not 18-0305-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I buy this gasket separately if I already have the 18-8515 kit?\u003c\/strong\u003e You can order 18-0305-1 individually as a replacement gasket even though it is also included in the 18-8515 mounting kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich manifolds require this specific gasket?\u003c\/strong\u003e Manifolds 18-1929 (starboard) and 18-1933 (port) both use gasket 18-0305-1 at the elbow connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or aftermarket?\u003c\/strong\u003e 18-0305-1 is a Sierra-branded exhaust elbow gasket, not an unbranded aftermarket substitute.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order this gasket?\u003c\/strong\u003e Ordering 18-0305-1 provides the single exhaust elbow gasket component only.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988061466843,"sku":"SIE-18-0305-1","price":9.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0305_lg__58964.1558119547.500.750.jpg?v=1785329158","url":"https:\/\/www.goodvibesmarina.com\/products\/exhaust-elbow-gasket-18-0305-1-oem-96108-for-crusader-7-4l-454-gm-big-block-v8-manifolds-18-1929-18-1933","provider":"Good Vibes Marina","version":"1.0","type":"link"}
