Specifically design for racing applications only, this thing works! We first started testing our new design back in 2021. We previously were using Koyo racing radiators but on hot day at 90 degrees or more we were experiencing overheating issues which caused us to end our 20 minute sessions of road racing early. Now on 90+ degrees days we have not seen track temps exceed 183 with the new radiator. This is a very well-built dual pass tube and fin style radiator. Additionally, we added a 1/4 inch NPT bung designed to work with a standard ATV fuel valve to make draining and bleeding a breeze since there is no mess. This is made to order so please allow 4 weeks for production.
