1968-1977 GM A-Body with LS Swap Aluminum Performance Dual Flow Radiator and 14 Inch fan kit. Meant to be used with an external trans cooler. 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. 100 percent TIG welded Fan Diameter 12 Inch All Aluminum (2) 1.25 inch Tubes Polished OE style tanks 16 fins per inch Corrugated fins that give more surface area and more thermal transfer Pressure tested Dual Flow Design Direct fitment for 68-77 A-Body LS Swaps Old Part Number: RPE546AK Radiator Specs Core Height 18.4 inch Core Width 28.5 inch Overall Height 18.82 inch Overall Width 34.21 inch Overall Thickness 3 inch Upper Hose 1.25 inch Lower Hose 1.5 inch Tubes (2) 1.25 inch Tubes
