Summit Racing™ Forged Crankshafts

4.1 out of 5 stars 10 Customer Reviews

Summit Racing™ forged crankshafts offer maximum strength and the best value for your dollar! Our crankshafts are non-twist forged from certified 4340 steel. They are put through several stages of heat-treatment, and then stress-relieved and shot-peened to provide the strength and reliability you demand for your high performance application. Each journal is micro-polished and a .125 in. radius is used for increased strength. Summit Racing™ forged crankshafts help you get the most in value and performance.
