DeWitts Direct Fit® LSX-SERIES aluminum radiators are engineered to simplify the installation of your LS Engine swap. This custom package is designed to fit the original mounting conditions and provide you with engine matching hose connections. Our standard LSX configuration has both inlet and outlet on the passenger side. Each package includes an electric fan with the temperature switch mounted in the end tank. We also include a steam line connection, custom billet DeWitts radiator cap, and complete electrical wiring kit.  

 Our Direct Fit® aluminum radiators feature factory type press formed end tanks, serpentine fins, and the factory type upper and lower channels. Each radiator core is assembled and brazed in our state of the art aluminum brazing furnace. DeWitts radiators are also epoxy free and come with a limited lifetime warranty.  Direct Fit® is our official trademark and it means your radiator will fit, without modifications.
