Eagle Chevrolet 4.125in Stroke Internal Balance Forged 4340 Steel Crankshaft

The Eagle 435041256000 is a high-performance forged 4340 steel crankshaft designed for Small Block Chevy engines. It is built to withstand demanding applications, capable of supporting up to 1500 horsepower. The manufacturing process includes non-twist forging, multi-stage heat treatment, stress relieving, and shot peening for enhanced durability. Each crankshaft undergoes rigorous quality control, including X-ray, magnaflux, and sonic testing. Key features for improved performance and longevity include chamfered oil holes for better lubrication and a .125 inch radius on rod and main journals for increased strength (requiring the use of chamfered bearings). The journals are precision-ground and micro-polished, and the crankshaft boasts a tight bob weight tolerance to minimize balancing time. This product can expose you to chemicals, which are known to the State of California to cause cancer. For more information, please refer to www.P65Warnings.ca.gov.
