SBF 347 Stroker Eagle Crankshaft Forged, 3.400 Stroke 430234025400

Eagle crankshafts are forged 4340 steel making them great for high performance engine applications. Eagle cranks feature non-twist forgings and go through a multi-stage heat-treatment processes. In addition each crankshaft is stress-relieved, shot-peened, X-rayed, magnafluxed, and sonic-tested. Eagle forged crankshafts have chamfered oil holes for improved oiling and large .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 1500 horsepower.
