The journals are precision-ground and micro-polished to less than 5 R.A. for optimal performance and durability. While this crankshaft requires narrow bearings, rod and main bearings are not included.\n\nFurther enhancing its performance capabilities, the crankshaft has chamfered oil holes for improved lubrication and a .125-inch radius on rod and main journals for increased strength. A target bob weight of +\/- 2 percent significantly reduces balancing time during assembly.","brand":"Eagle Specialty Products","offers":[{"title":"Default Title","offer_id":52872899690808,"sku":"EAG435334805700","price":838.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/forged-4340-steel-crankshaft-3-480-stroke-1-piece-rear-main","provider":"MOTORMIA","version":"1.0","type":"link"}
