Upgrade your cooling system with our new 57mm double row aluminum radiator for all C7 Corvettes. This new Direct Fit® radiator features serpentine fin and special dimpled cooling tubes. These dimples create turbulence as coolant passes through the tube. Turbulent flow is a proven method to increase heat transfer over the standard lamar flow method. The thicker core increases tube-to-fin surface area and the all aluminum construction eliminates plastic end tanks and gasket failures. The larger capacity end tanks hold one additional gallon of coolant to help dissipate heat.
