Pro vs HP Series
DeWitts PRO Series all aluminum radiators provide optimum cooling in a two-row design. The 2.25" thick core, with louvered fin, has been tested for decades in the most rigorous conditions. They measure similar in thickness to a standard four core copper radiator while outperforming them by 30%. A top choice for all makes, models, years and every engine combination.
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 an elevated continuous air flow to optimize cooling efficiency.
