Cold Case Radiators GMT556A21K - 77-87 Chevy/GMC Pickup Truck 21 Inch Aluminum Radiator AT and 12 Inch Fan Kit

1977-1987 Chevy/GMC Truck Aluminum Performance Radiator.

This is the radiator that is 21 inches high overall. For the 19 inches high version, see GMT556AK

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.
