{"product_id":"4-150-inch-stroke-forged-crankshaft","title":"4.150-Inch Stroke Forged Crankshaft","description":"The Eagle Specialty Products EAG444041506760 crankshaft is engineered for high-performance Mopar RB-Series and 426 Hemi applications. It boasts a robust 4.150-inch stroke and internal balance, ensuring smooth operation and enhanced power delivery.\n\nConstructed from certified forged 4340 steel, this crankshaft undergoes a multi-stage heat treatment process for exceptional strength and durability. The surface is nitrided to provide superior wear resistance, while the journals are micropolished to achieve a finish of 2 RA or better, promoting optimal lubrication. Optimized oiling passages ensure consistent journal lubrication, and the target bobweight is guaranteed within a +\/- 2% tolerance for more predictable balancing.\n\nThis crankshaft features a 2-piece seal design and a 6-bolt rear flange. It requires chamfered or narrowed bearings due to its .125-inch fillet radii, which enhance strength and rigidity. Eagle emphasizes their commitment to quality through rigorous testing, including X-ray, magnafluxing, and sonic testing, ensuring reliability for the most demanding applications.\n\nNote: All items are not for use in pollution-controlled vehicles.","brand":"Eagle Specialty Products","offers":[{"title":"Default Title","offer_id":52872893989176,"sku":"EAG444041506760","price":1124.97,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-150-inch-stroke-forged-crankshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
