American Expedition Vehicles is selling a complete off-road transformation for the Ford Super Duty, and it wants $19,999 for the privilege. The FX370 kit bundles everything from 37-inch tires to front and rear bumpers into a single box, pitched as the antidote to the parts-bin chaos that drags most truck builds into months of frustration.
The concept is simple. Instead of sourcing a lift kit from one company, tires from another, bumpers from a third, and then praying it all plays nice together, AEV engineered the whole package as a system. Every component is designed to work with the factory Super Duty architecture, which means no trimming fenders in the driveway and no mysterious rubbing noises at full lock.
At the center of the kit sit 37-inch BFGoodrich All-Terrain T/A KO3 tires on AEV’s own 18-inch wheels. A four-inch suspension lift with Bilstein dampers tuned specifically by AEV provides the clearance. The company even recalibrates the speedometer and replaces the door-jamb tire pressure sticker with one reflecting the new rubber, a small detail that separates a proper engineering package from a pile of bolt-ons.
The hardware extends beyond ride height. A stamped-steel front bumper accommodates a winch and includes integrated recovery points. Out back, a high-clearance rear bumper improves departure angle, also with recovery points. A matte black graphics package running along the doors and bed sides rounds out the visual transformation.
AEV is making an interesting play by marketing this not just to weekend trail runners but to commercial fleet operators. The pitch is uptime. Buy everything at once, install it in a single session, and get back to work instead of waiting on back-ordered parts or making second trips to the shop when the suspension doesn’t agree with the bumper geometry.
Twenty grand is not pocket change, especially on top of a truck that already costs north of $45,000 in most configurations. For buyers who want off-road capability straight from the dealer, Ford’s own Tremor package starts at $4,450, though required options like four-wheel drive and the mandatory crew cab push the real cost of entry to around $13,575 on an XLT. The Tremor rides on 35-inch tires, two inches less than the AEV setup, and doesn’t include the bumper upgrades or recovery hardware.
That price gap tells you exactly who AEV is chasing. This isn’t for the buyer cross-shopping Tremor stickers at the Ford dealer. It’s for the owner who already has a Super Duty in the driveway, knows exactly what 37s will do on a Forest Service road, and wants the job done right without becoming a project manager.
For those who find 37 inches insufficient, AEV also offers a kit that pushes the Super Duty onto 40-inch tires. That setup starts moving the truck from capable daily driver into dedicated overlander territory.
The turnkey model has been gaining traction across the aftermarket industry as buyers increasingly resist the time and risk of piecing together modifications. AEV built its reputation doing exactly this kind of work on Jeeps and Chevrolets. The Ford Super Duty expansion puts the company squarely in the middle of the hottest truck segment in the country, competing not just with other aftermarket shops but with factory packages from Detroit itself.
Whether $19,999 buys peace of mind or just a premium markup on parts you could source yourself depends entirely on how much you value your weekends.
