The only caveat to what’s already been said is the FX4 package also gets you the 3.73 rear axle (and HD radiator). Full 9000lb towing requires the brake controller which can be had as a dealer installed option...

Hate to bring an old topic back up but I used the search button and didn't feel the need to make a new thread. Quick question on this same topic have the 2016 Expedition El 3.5l 4x4 which has the 3.73 rear end. I'm looking to boost the tow capacity as the trailer I'm looking at weighs 7146 GVWR. I have installed aftermarket 7pin trailer wire and a brake controller. If I was to get a auxillary trans cooler and an upgraded radiator would that do that truck. Also suggestions for both as well would be awesome! Thanks a bunch!
