Show original supplier description
The Eagle Specialty Products 103503750 is a cast steel crankshaft engineered for stroker applications, offering a reliable and economical upgrade for your engine build. This crankshaft features a 3.750-inch stroke, providing a significant increase in displacement. It is designed with an external balance configuration and utilizes a 2-piece rear main seal for compatibility with many engine setups. Constructed from durable cast steel, this crankshaft is built to withstand the demands of performance applications. It features a journal finish of 6 R.A. or less for improved efficiency and reliability, along with a target bob weight of +/- 2 percent to simplify balancing. The crankshaft snout style is standard, and it requires a 7/16 in.-20 balancer bolt thread size. It is not lightened and does not require narrow bearings. Please note that rod and main bearings are not included with this crankshaft. This crankshaft is specifically intended for stroker applications and is recommended for use in pump-gas, naturally-aspirated, non-competition road cars. It is crucial to ensure this crankshaft is compatible with your specific vehicle year, make, and engine application before installation.
