Be Cool, America's leader in power cooling technology, once again sets the standard with their Circle Track Series Aluminum Hard Core Racing Radiators. These crossflow radiators feature a performance-grade, dual 1-inch core with ''form-folded'' and tapered tanks. With this tank design the easy-fill billet filler neck with high-capacity overflow tube is placed horizontally to eliminate air pockets and insure the cooling system is completely full. These single pass design models feature a 1-1/2'' slip-on upper and 1-3/4'' lower hose outlet with the lower outlet placed at an angle in a location to clear the chassis to facilitate fast, easy lower hose removal. Additionally, all versions of the Circle Track Series Hard Core Racing Radiators are constructed with ''twist resist'' upper and lower protective aluminum core rails for extra rigidity and are designed for simple yet effective universal cradle mounting. Each radiator is 100% pressure tested before being shipped in expanding foam packaging. Made In The USA! Don't forget to add a Be Cool Hard Core Race Radiator Cap to complete the package!
