Eagle 2013+ Chrysler Modern Hemi 4340 Steel Crank

These forged 4340 steel crankshafts from Eagle Specialty Products are suitable for high-performance applications. They feature non-twist forging, a multi-stage heat-treatment process, are stress-relieved and shot-peened. Each crank undergoes X-ray, magnaflux, and sonic testing. They have chamfered oil holes for improved oiling and a .125 in. radius on rod and main journals for increased strength (requiring chamfered bearings). All journals are precision-ground and micro-polished to less than 5 R.A. A target bob weight of +/- 2 percent reduces balancing time. Eagle crankshafts are rated to support up to 1500 horsepower.
