Eagle Specialty Products lightweight 4340 crankshafts offer strength, durability, and lighter weight at competitive prices. These non-twist forged crankshafts pass through a multi-stage heat-treatment process and are magnafluxed and sonic-tested to ensure quality. Each journal is micro-polished and a radius of .125 in. is used to increase strength, as the lightening holes in every rod throw reduce weight. Eagle Specialty lightweight crankshafts bring you unsurpassed quality and weigh only 48 to 49 lbs.
