Nobody else stands behind their product like we do. We can proudly offer this guarantee to you since all of our radiators are 2-rows with 1.0" tubes, fully TIG welded with billet filler necks, heavy duty plate transmission coolers and free of 3-row and 4-row gimmicks. NO 3 ROW GIMMICKS Are you're confused about 2-rows, 3-rows and 4-rows? Confused about the difference between copper and brass radiators? That's understandable. In fact, the companies that sell the 3-row and 4-row snake oil radiators are hoping that you are confused. You don't have to be confused and have the wool pulled over your eyes. You can see our simple guide that takes all of the old wives' tails out of how aluminum radiators work and how many rows are best. You can see our 2 Row Versus 3 Row Versus 4 Row Guide here. Our 1955, 1956 and 1957 Tri-5 aluminum radiators are direct bolt-ins for the original V8 copper/brass radiators and 6 cylinder cars. For original V8 SBC cars, use our part number 1427 which mounts on the engine side of the core support (V8 mounting position). For original 6 cylinder cars that now have a SBC or BBC, use our part number 1425. It mounts on the grill side of the core support (6 cylinder mounting position). Our 6 cylinder model is available with an ultra high power electric fan and aluminum shroud setup. QUESTIONS? CALL FRANK YOUR 1955 - 1957 CHEVY TRI-5 EXPERT (773) 599-3067
