63-66 Chevy/GMC Pickup Truck Aluminum Performance Radiator

1963-1966 Chevy/GMC Pickup Truck Aluminum Performance Radiator. For trucks with heavy duty 4 core mounts.

Also will fit some: 1961-1964 Grand Prix and 1961-1964 Bonneville/Catalina.

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. 

For the Black Powder-Coated version, use part # GMT555AB. With our Night Rider Black series, you will be hard pressed to find a difference between an original versus a COLD-CASE.
