    Chevrolet Performance Crankshafts are a strong, durable choice for when rebuilding or refreshing your performance engine. The engineers at Chevrolet know how catastrophic crankshaft failure can be so that's why their crankshafts are made to exact specifications and then tested to handle the force of high-performance applications. These tough crankshafts are the same ones used in Chevrolet Performance Crate Engines. Featured in either cast iron or forged finish and available for popular small block, big block and LS series engines.
