{"product_id":"forged-4340-steel-crankshaft-4-000-stroke-1","title":"Forged 4340 Steel Crankshaft, 4.000\" Stroke","description":"The Eagle Specialty Products Forged 4340 Steel Crankshaft is engineered for high-performance applications, offering superior strength and reliability. Constructed from premium forged 4340 steel, this crankshaft features a non-twist forging process and a multi-stage heat-treatment for enhanced durability.\n\nKey specifications include a 4.000 in. stroke, internal balance, and a standard snout style. The journals are precision-ground and micro-polished to less than 5 R.A., with .125 in. fillet radii on both rod and main journals to maximize strength. Oil holes are chamfered for improved lubrication, and the crankshaft requires narrow bearings. The target bob weight is within +\/- 2 percent, significantly reducing balancing time. It is designed for Ford 351W engines and has a 5\/8 in.-18 balancer bolt thread size.\n\nIt is sold individually and is compatible with both 1-piece and 2-piece rear main seal configurations. Please note that this crankshaft requires balancing to match your specific rods and pistons.","brand":"Eagle Specialty Products","offers":[{"title":"Default Title","offer_id":52872904016184,"sku":"EAG435140006200","price":836.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/forged-4340-steel-crankshaft-4-000-stroke-1","provider":"MOTORMIA","version":"1.0","type":"link"}
