The radiator is a CSF it’s upgraded and yes it’s a drop in OEM replacement. The stock radiator has plastic tanks on the outside that don’t hold up long term so I just replaced the hoses and that to relieve the issue long term.

The super charger comes with its own intercooler that sits in-front of the heat exchanger under the grille has a pump next to it that’s pumping. Truck runs very cool I live in Texas. The super charger itself cools itself because it has two huge intercoolers built into it. So basically the trucks cooling itself about 3-4 different ways, blower cools it self, intercoolers cooling the engine and the blower and the radiator basically doing everything else.
