    Premium Cranks for Engine Builds

    Eagle ESP Forged 4340 Steel Crankshafts feature exceptional strength and unsurpassed quality at a reasonable price making them a perfect choice for high-performance applications. These cranks start as forged 4340 steel non-twist forgings that undergo a multi-stage heat treat process. Eagle machinists then x-ray, magnaflux and sonic tests each crank to ensure it is free of cracks, air pockets and any imperfections that could occur during the forging process. Afterward, each crankshaft is stress relieved and shot-peened for durability and longevity. Eagle also guarantees a target bobweight +/-2% that reduces balancing time!
