{"product_id":"4-300-inch-stroke-cast-steel-crankshaft","title":"4.300-inch Stroke Cast Steel Crankshaft","description":"The Eagle BB Ford Cast Steel Crankshaft, model CRS-104604300, is a robust upgrade from Original Equipment (O.E.) crankshafts. Designed with a 4.300-inch stroke and internal balance, it features a 2-piece rear main seal and is constructed from cast steel, offering improved strength compared to cast iron alternatives.\n\nThis crankshaft is specifically recommended for naturally aspirated, pump-gas street cars that are not used for competition. It incorporates .092-inch fillet radiuses to increase strength and utilizes O.E. style straight oiling passages. The journals are micropolished to typically achieve a finish of 5 RA or better, ensuring smooth operation. Eagle guarantees the target bobweight within a +\/- 2% tolerance for more predictable balancing.\n\nIt is important to note that the crankshaft must be balanced to match your specific connecting rods and pistons. This component serves as an excellent alternative to O.E. crankshafts, providing enhanced durability and performance for street applications.","brand":"Eagle","offers":[{"title":"Default Title","offer_id":52687897592120,"sku":"CRS-104604300","price":561.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662656695.webp?v=1784887151","url":"https:\/\/store.motormia.co\/products\/4-300-inch-stroke-cast-steel-crankshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
