The Eagle 104564250 crankshaft offers an upgrade from original equipment crankshafts for 1991-2000 Chevy V8 7.4L/454 Big Block engines. This cast steel crankshaft features a 4.250-inch stroke and an externally balanced design, providing increased strength with its .092-inch fillet radii while still allowing the use of O.E. replacement bearings. Constructed from certified steel, this crankshaft undergoes multi-stage heat treating, sonic testing, magna-fluxing, and x-ray inspection to ensure a reliable product. Eagle Specialty Products emphasizes quality and value, making this crankshaft a recommended choice for pump-gas, naturally-aspirated, non-competition road cars. Eagle Specialty Products has a long history in developing engine internal components for the automotive performance market. Their commitment to quality and affordability is evident in their extensive product line, which spans various automotive manufacturers. All parts are special order from the manufacturer, and if delivery time is a concern, customers are advised to contact the seller for stock status to avoid cancellation fees.
