These LS1 conversion radiators are built with the correct inlet and outlet required for the engine swap. They are 100% TIG welded, 100% pressure tested and use no epoxy or sealers. These Double Pass radiators were designed for the rigors of racing, but we added the mounts to allow their superior design on the street. After all, there are more important things to be doing than installing your radiator - like enjoying your car on the road!
NOTE: BB cars may require use of small block radiator rubber mounts.
