COLD-CASE Radiators Aluminum Performance Radiator; 21-Inches High

1977-1987 Chevy/GMC Truck Aluminum Performance Radiator. This is the radiator that is 21 Inch high overall. See GMT556A for the
19 Inch high version.
1.25" Upper and 1.5" Lower Hoses. For other configuration, see GMT556A21.

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.
