Eagle Cast Steel Crankshafts
Eagle cast steel crankshafts are the most dependable option when you don't want to break the bank. Each crank is inspected for dimension, size, and stroke accuracy. For improved efficiency and reliability, they have a journal finish of 6 R.A. or less and a target bob weight of +/- 2 percent for easy balancing. The crankshaft is the heart of your engine, so demand the best—order the Eagle Specialty model and performance options recommended for your vehicle year, make, and engine application.
