This brand-new, 2-row 20-inch radiator is made from high-quality aluminum. It features 2 rows of extra-large, 1-inch tubes for 4-row efficiency minus the added weight, weighing in at 5-7 fewer pounds. The original, stock radiators for 1967-1969 Mustangs had trouble distributing the hot water to the far-right side of the radiator. This radiator, however, is equipped with Scott Drake's specially designed, extensively tested baffle, which works to dispense the flow of hot water throughout the radiator evenly. This radiator includes a transmission cooler. Its inlet diameter measures 1-1/2 inches and its outlet diameter measures 1-3/4 inches.
