2011-2016 Duramax Max-Flow Arctic Radiator (MAX-RAD-1116)

The Max-Flow Arctic is a high flow replacement radiator for the LML Duramax, reinforced in all critical areas to exceed OEM specifications. Every unit is checked for damage before it ships and is packed in triple wall cardboard, and it is the only radiator DmaxStore installs in house. It is a smart replacement once the factory radiator is past 200k miles or while you are already replacing the water pump or transmission coolers.
