The Eagle Specialty Products 103514000 is a cast steel crankshaft built for performance and dependability without a high cost. Each crankshaft undergoes inspection for precise dimension, size, and stroke accuracy, ensuring a reliable foundation for your engine build. For enhanced efficiency and reliability, these cranks feature a journal finish of 6 R.A. or less, along with a target bob weight of +/- 2 percent, simplifying the balancing process. This crankshaft offers a 4.000-inch stroke, making it suitable for stroker combinations.
