Cranks made of forged steel are very cost-effective and strong. By using the latest forging and machining technology, we offer the best crankshafts available on the market today. In order to reduce stress and optimize tensile strength, all crankshafts are made of forged steel, which is hardened and tempered on the core. For the best base for your rebuild, we design our crankshafts to meet or often exceed original tolerances.
