This Ford Super Duty Can Now Run 40-Inch Tires and It Is Still Streetable

When Big Isn't Big Enough

There's no doubting the size of Ford's Super Duty range of pickup trucks. The "smallest" version one can get is already 232 inches long, 80 inches wide, and rides on a 141.4-inch wheelbase. Describing size is subjective, but its dimensions firmly put it in the massive category.

Speaking of massive, one can get a Super Duty in many shapes, sizes, trims, and engine choices. Aside from the standard trims, the pickup can be specified with the off-road-oriented Tremor package and luxed up with the King Ranch or Platinum trims.

Of course, there are those who want more from their Super Duty. Anyone who wants to do so can turn to American Expedition Vehicles or AEV to make that happen.

AEV is Expanding its Portfolio

AEV is normally associated with Jeep. After all, the company got its start by upfitting Wranglers, although it has since added Ram pickups and GM products to its list of vehicles that can be upgraded. Now, they're venturing into new territory with Ford as part of its expansion.

With that, AEV has made an upgrade package for the Super Duty. Its mods now allow owners to fit whopping 40-inch tires to the pickup, and the company claims the changes made do not come at the expense of drivability. Prior to that, the biggest factory tire available for the Super Duty was 35 inches.

The AEV FXL Package in a Nutshell

So, what did AEV do for the Super Duty? The highlight here has to be the four-inch DualSport XP Suspension lift kit, as if it needed any more ground clearance. It's then complemented by a set of AEV-tuned Bilstein dampers all around. For those massive 40-inchers to fit, the pickup gets HighMark fender flares, and those 18-inch Katmai DualSport wheels look positively tiny when shod in those chunky BF Goodrich HD-Terrain tires.

Other goodies? There's a stamped steel front bumper and a high-clearance rear bumper to maximize the lift by giving the Super Duty better approach and departure angles. The steel bumper at the front also includes a built-in winch and foglights. One can also go for the FXL graphics pack, and it even comes with a serialized plaque. By the way, all the mods do not interfere with the vehicle's advanced driver assists, and it even includes a three-year/36,000-mile warranty.

How Much for the Conversion?

For now, AEV hasn't listed the total cost for the whole package. That said, we reckon it won't be cheap. Still, the company is known for strong and sturdy bids, and it'll be worth it for anyone who plans to give their Super Duty the FXL treatment.

We'll know more about it once the Super Duty FXL makes its public debut at the 2026 North American International Auto Show. It's not that long of a wait, either, as doors open to the public on January 14.
