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" tubes, aluminum fan shroud and dual 14" 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.
