Eagle Forged 4140 Steel Crankshafts

The Eagle Forged 4140 Steel Crankshafts are great for any high performance applications. They feature non-twist forging, go through a multi-stage heat-treatment process, are stress-relieved and shot-peened. These cranks are X-rayed, magnafluxed and sonic-tested, so you know you're getting a top-quality piece. Each crankshaft has chamfered oil holes for improved oiling, a .125 in. radius on rod and main journals for increased strength so chamfered bearings are required. All journals are precision-ground and micro-polished to less than 5 R.A. A target bob weight of +/- 2 percent greatly reduces balancing time. Eagle crankshafts are rated to support up to 1000 horsepower!
