1977-1987 Chevy/GMC Truck 21 Inch LS Swap Aluminum Performance Radiator and 14 Inch Fan Kit. This is the radiator that is 21 inches high overall and has the steam port for an LS Swap. External trans cooler is recommended. When you need the biggest and best, look no further than the Cold Case Super Duty Line. All Super Duty kits include 2 row radiators with 1.25 Inch tubes, aluminum fan shroud and dual 14 Inch fans, flowing at 2200cfm per fan! For extreme horsepower applications OR if you just want the best of the best... These COLD-CASE radiators are Tig welded 100 percent aluminum and absolutely beautiful. Don't buy a 3 or 4 row aluminum radiator! It doesn't cool as good as these oversize 2 row models. These radiators are original appearing and have the correct stamping. Once painted, you'd be hard pressed to find a difference over an original versus a COLD-CASE.
