Crane Mechanical Roller Camshafts

Crane mechanical roller camshafts are not for the weak of heart. These units are engineered for operation at ranges that can exceed 10,000 rpm--the perfect blend of performance and efficiency. While a large number of mechanical roller cams are used in purely competition applications, Crane also manufactures less severe roller grinds designed for high performance street engines with higher compression or power-adders. Crane Cams has the industry's largest database of camshaft profiles. This enables Crane to provide you with camshafts that are ideally suited for your application. If you own a power-eating mean machine, Crane has the perfect camshaft for you!
