Description

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.
Lower Hose for 4WD/1.75" outlet vehicles: Gates 20694 or Dayco 70664.

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 # GMT556A21B. With our Night Rider Black series, you will be hard pressed to find a difference between an original versus a COLD-CASE.

It didn't fit my truck, it was to narrow for the brackets to properly fit on the radiator, great quality though.

Review: 5 Stars - Very Satisfied

Great looking, fitting and cooling radiator

The reason for my ratings is Cold Case Radiators was easy to deal with and the build quality is outstanding.
