{"product_id":"forged-4340-crankshaft-4-150-stroke","title":"Forged 4340 Crankshaft, 4.150\" Stroke","description":"The Eagle Specialty Products forged 4340 steel crankshaft is engineered for demanding, high-performance engine builds. It features a 4.150-inch stroke and internal balancing for smooth operation. The crankshaft is constructed from forged 4340 steel, ensuring exceptional strength and durability under high stress.\n\nThis crankshaft undergoes a rigorous multi-stage heat-treatment process, followed by stress relieving and shot peening to further enhance its resilience. Each unit is meticulously inspected through X-ray, magnaflux, and sonic testing to guarantee top-tier quality and reliability. For improved lubrication, it includes chamfered oil holes and .125-inch radius on rod and main journals for increased strength.\n\nThe precision-ground and micro-polished journals feature a finish of less than 5 R.A. for optimal bearing performance. Additionally, a target bob weight of +\/- 2 percent significantly reduces balancing time, making installation more efficient. This crankshaft requires narrow bearings for proper fitment.","brand":"Eagle Specialty Products","offers":[{"title":"Default Title","offer_id":52872895103288,"sku":"EAG444241506760","price":909.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/forged-4340-crankshaft-4-150-stroke","provider":"MOTORMIA","version":"1.0","type":"link"}
