Cold Case Radiators GMT558ALSK Features:

1967-1976 GM Truck LS Swap Aluminum Performance Radiator and 12 Inch Fan Kit. To run an LS swap on your classic truck, you can run this radiator and either run a separate transmission cooler or re-route your trans lines to the driver side of the radiator 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.Fits:1967-1976 GM Truck LS SwapDetails:100 percent TIG weldedFan Diameter 12 InchAll AluminumPolished OE style tanks(2) 1.25 inch Tubes16 fins per inchCorrugated fins that give more surface area and more thermal transferPressure testedFor automatic transDirect fitment for 77-87 GM Truck LS Swap trucksRadiator SpecsCore Height 18.4 inchCore Width 28.5 inchOverall Height 18.82 inchOverall Width 34.21 inchOverall Thickness 6 inchUpper Hose 1.50 inchLower Hose 1.50 inchTubes (2) 1.25 inch Tubes
