High-Horsepower street cars and trucks can be a challenge to keep cool. A proper cooling system starts with the right radiator. Aluminum Radiators cool more effectively and weigh less than older stock style brass units. Note: Frostbite 3 and 4 row radiators will be thicker than stock and can extend into engine bay further interfering with some stock fan/clutch applications. Existing cooling fan modifications may be required during installation. Electric fan and shroud options are available to eliminate stock clutch/fan.
