Two intercooler options if you count aftermarket.

I asked "which 3.5?" because not everyone that posts about having Max Tow actually has max tow, and not everyone knows the difference between an intercooler and a condenser.

It's common for some to make sure everyone is on the same page before throwing suggestions out there.

 

Angled safety chain eyelets and all.

Will confirm max tow radiator part #. Is the trans cooler a direct swap from the SD? OEM the best/only choice here?

And...aftermarket intercooler?

 

I haven't done the work myself, but that is my understanding with the trans coolers. You could probably confirm by looking at photos of each.
