Specialty Products BB Chev 396 & 427 Forged 4340 Crankshaft 3.766 Stroke 6.135 Rod Internal Balance
Product Information
These forged 4340 steel crankshafts from Eagle Specialty Products are great for high performance applications.
They feature non-twist forging, go through a multi-stage heat-treatment process, and 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, and the journals are precision-ground and micro-polished to less than 5 R.A. A target bob weight of +/- 2 percent greatly reduces balancing time.
