1967-1976 GM Truck LS Swap Aluminum Performance Radiator and 14 Inch Fan Kit. 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... To run an LS swap on your classic truck, you can run this radiator and run a separate transmission cooler OR run our GMT558A standard high flow C10 radiator with a 2 piece upper hose that goes to the drivers side inlet (use a 'T' fitting in between the 2 hoses for the steam port). 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.
