{"product_id":"ls9-head-gasket-4-100-bore","title":"LS9 Head Gasket 4.100\" Bore","description":"The BTR LS9 Head Gasket is engineered for performance and value, making it an excellent choice for budget power adder builds. This gasket is constructed from 7 layers of multi-layered steel, providing a robust seal capable of reliably handling over 1,000 horsepower.\n\nKey specifications include a 4.100-inch bore opening and a compressed thickness of .055 inches. These features are designed to work effectively with LS9 cylinder heads and are a direct replacement for GM part number 12622033. The gaskets are sold as a pair.\n\nWhile the product is generally versatile for LS engines, it's important to note that this specific gasket (BTR22033-2) is recommended for aftermarket cylinder heads, as it will NOT work with a Trick Flow Fast As Cast LS1 head. Always verify compatibility with your specific cylinder head and engine combination.","brand":"BTR","offers":[{"title":"Default Title","offer_id":52687276769592,"sku":"BTR22033","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660190027.webp?v=1784882126","url":"https:\/\/store.motormia.co\/products\/ls9-head-gasket-4-100-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
