Crane's mechanical roller camshafts are not for the weak of heart. These camshafts are engineered for operation at ranges that can exceed 10,000 rpm and are 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 that are designed for high performance street engines that have higher compression or power-adders. (For best results, the valve lash must be checked and set periodically.) 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 have a power-eating mean machine, Crane has the perfect camshaft for you!
