Cold Case Radiators - GMT558ALSK - 67-76 Chevy GMC Pickup Truck LS Swap Aluminum Radiator AT and 12 Inch Fan Kit

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.
