Summit Racing™ Pro LS/LT Factory Camshafts
Summit Racing™ Pro LS/LT Factory Cams are offered as an affordable, high quality, option to replace a worn or damaged factory camshaft. The cams are built for dependability, made on 5150 bearing steel blanks and finished on CNC grinders and polishers. These grinds are identical to factory, so no changes should be expected in emissions or tuning. Make sure to check them out on your next rebuild or AFM repair.
