To satisfy all our cooling needs this US Radiator aluminum radiator/electric fan combo was ordered. The aluminum radiator is a high efficiency two-row radiator with 1-inch tubes and 18 fins per inch. There was enough room for one fan-which US Radiator offers-but I opted to up the ante with dual 11-inch Spal fans. The great thing about US Radiator is they will custom make a radiator and shroud per your dimensions, which makes everything simple, efficient, and clean. They even equipped the radiator with tranny cooler line fittings for the Gearstar 4L60 tranny.
