You've already got the biggest radiator available for the truck in a direct swap setup. You go bigger, you start running into fitment issues in other areas.
Also, it would be beneficial to swap the fan clutch since you've gotta pull the fan anyway. Especially if it's got the kind of mileage the truck has.
I don't know if there's any truth to this, but apparently 2006 fans differ from 05 and earlier fans. Something about blade angle combined with different clutch? Someone told me this years back and I never researched it. Unknown if it or the clutch will fit your 4.0 OHV.
e-fans are problimatic because 99% of people with them either crimp connector them, dont install them correctly, or try running too much power through tiny relays/switches.
an e-fan isnt any more problematic then a clutch fan spinning 24/7 wearing out your waterpump bearings quicker then needed.
There are radiators you can add, you shouldnt need one. for the money it wont be worth it. an e-fan though, is a great way to save some gas and free up a little throttle response. I love mine, it works beautifully. the truck warms up faster, the AC blows colder, my MPG went up.
