This radiator comes with a high performance internal 7 plate transmission cooler that is 3x the cooling capability of the OEM cooler

The standard core for this custom built, high performance radiator features 2 rows of 1" tubes. The tubes are space 3/8" apart, on center. With 3/8" centers we are able to put more rows of tubes, fins, and coolant volume in the core as well as create more surface area for air to travel over; allowing for greater heat dissipation.
