When replacing your radiator, think twice before installing just any radiator. Get a CARS Inc. all aluminum radiator. The radiator is built to strict factory measurements for easy bolt-in applications. CARS Inc. now carries aluminum radiators for your 1955, 1956 and 1957 Chevrolet. These beautifully crafted radiators are completely CNC welded. The radiators have a two row tube system with 27 millimeter tubes and 15 fins per inch, giving your radiator a much larger cooling surface area. The radiators have a billet neck and come with a pet-cock. The transmission cooler is standard in all of our radiator units. The radiators also have been made to install a temperature sender (not included).
