{"product_id":"forged-4340-crankshaft-4-000-inch-stroke","title":"Forged 4340 Crankshaft, 4.000-inch Stroke","description":"The Eagle Specialty Products 435640006000 is a forged 4340 steel crankshaft engineered for high-performance engine builds. This crankshaft offers a 4.000-inch stroke and features internal engine balance, making it suitable for demanding applications. Constructed from high-strength 4340 steel, it undergoes a multi-stage heat-treatment process, is stress-relieved, and shot-peened for enhanced durability and reliability.\n\nFor improved oiling, it features chamfered oil holes, and its rod and main journals have a .125-inch radius for increased strength. The journals are precision-ground and micro-polished to a finish of less than 5 R.A. A target bob weight of +\/- 2 percent helps reduce balancing time during assembly.\n\nKey specifications include a standard snout style, 2.100-inch rod journal diameter, and 2.750-inch main journal diameter. It requires narrow bearings, and rod and main bearings are not included. This crankshaft is designed for Ford 351C and modified engines and features a 351W snout. Note that when used in a Cleveland engine, it requires a 0.375-inch spacer behind the timing gear or a special timing chain set.","brand":"Eagle Specialty Products","offers":[{"title":"Default Title","offer_id":52872898773304,"sku":"EAG435640006000","price":975.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/forged-4340-crankshaft-4-000-inch-stroke","provider":"MOTORMIA","version":"1.0","type":"link"}
