DeWitts aluminum radiators are Made in Michigan and we control 100% of the manufacturing process in house. Our CAB brazing furnace allows us to produce the finest aluminum cores in the industry. We have the flexibility to build custom aluminum radiators in several tube widths and fin designs. DeWitts began building Direct Fit® Corvette radiators over 15 years ago. We have expanded our line to many other makes and models, using the same degree of attention.
