When I was looking for a radiator for my 6.4 Hemi swap I personally talked to the owner of C&R and he had a Jeep just like my that they designed the radiator for. I believe it was 2015 when AEV made the switch to C&&R. The older ones were made by Michigan Brazing, I was told. So I bought one and it never leaked a drop! The C&R also cooled better. I still have my AEV radiator,2014 model & it never leaked but I always err on the side of better performance. I'll sell my old one for a $100. to anyone who wants it. I'm in Northern Colorado. I think it would cost a fair amount to ship it though. I paid $1100. for the C&R radiator and I think it was worth the price.
