Eagle's commitment to quality and service has resulted in customer loyalty and satisfaction. This, in turn, has fueled rapid growth over the years. Eagle added crankshafts to our lineup a few years later as well as expanding our offerings in connecting rods. Continuous design improvements and improvements in materials and manufacturing techniques have resulted in Eagle being the largest and most respected aftermarket connecting rod and crank manufacturer in the industry. We never stop researching ways to make our products lighter, stronger, more efficient to manufacture, and more diverse. When you stop moving forward, you get passed by the competition.

Eagle forged 4340 steel crankshafts are great for high performance applications. They feature non-twist forging, undergo 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. Many options are available; order the model recommended for your year/make and engine application.
