DeWitts HP Series all aluminum radiators are made to order and built for high performance applications. Typical uses include track days and sustained high speed driving. The larger 1.25" tubes add additional surface and increased capacity. This increase in surface area requires a continuous elevated air flow to optimize cooling efficiency. Each DeWitts radiator is expertly TIG welded, free of epoxy, and comes with a limited lifetime warranty. This radiator features exact reproduction press formed end tanks and factory side mounting brackets.
The lower tank is thicker than the Pro Series radiator which may cause clearance issues with stock suspension. Please note that if a fan is selected there may be interference with the factory suspension (sway bar) on 1958-60 models.
