This is the radiator that is 21 Inch high overall. See GMT556A for the 19 Inch high version. 1.25 inch Upper and 1.5 inch Lower Hoses. For other configuration, see GMT556A21.\u003c\/p\u003e\u003cp\u003eThese 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.\u003cbr\u003e\u003cstrong\u003eDetails:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e100 percent TIG welded\u003c\/li\u003e\n\u003cli\u003eAll Aluminum\u003c\/li\u003e\n\u003cli\u003e2 Rows of 1.25 Inch tubes\u003c\/li\u003e\n\u003cli\u003ePolished OE style tanks\u003c\/li\u003e\n\u003cli\u003e16 fins per inch\u003c\/li\u003e\n\u003cli\u003eCorrugated fins that give more surface area and more thermal transfer\u003c\/li\u003e\n\u003cli\u003ePressure tested\u003c\/li\u003e\n\u003cli\u003eFor automatic trans\u003c\/li\u003e\n\u003cli\u003eDirect fitment for 77-87 GM Truck w\/ 1.5 inch Lower Hose\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eRadiator Specs:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCore Height 18.8 Inch\u003c\/li\u003e\n\u003cli\u003eCore Width 28.35 Inch\u003c\/li\u003e\n\u003cli\u003eOverall Height 21 Inch\u003c\/li\u003e\n\u003cli\u003eOverall Width 34.33 Inch\u003c\/li\u003e\n\u003cli\u003eOverall Thickness 3 Inch\u003c\/li\u003e\n\u003cli\u003eTubes (2) 1.25 Inch Tubes\u003c\/li\u003e\n\u003cli\u003eUpper Hose 1.25 Inch\u003c\/li\u003e\n\u003cli\u003eLower Hose 1.5 Inch\u003c\/li\u003e\n\u003cli\u003eTrans Cooler Fitting: 5\/16 inch Inverted Flare\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLD-CASE Radiators","offers":[{"title":"Default Title","offer_id":51232083149016,"sku":"GSWT_GMT556A21-1","price":435.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0684\/3180\/6680\/files\/GMT556A21-1-GSWT.jpg?v=1766638078","url":"https:\/\/www.truckandautopartsstore.com\/products\/77-87-gm-truck-21-inch-1-25-1-5-outlets-cold-case-radiators-cold-case-radiators-gmt556a21-1","provider":"Truck \u0026 Auto Parts Store","version":"1.0","type":"link"}
