If you want to turn your stock pickup truck into a true off-roader, there’s no shortage of aftermarket companies willing to help. And by “help,” I mean sell you parts that you then have to figure out how to make work together, while also keeping track of the small-ticket items that inevitably follow in their wake. That can cause a build to drag on and lose momentum like a truck spinning its tires on a steep dirt mound.
That’s where AEV’s FX370 turnkey kit for the Ford Super Duty comes in. It provides everything you need, all engineered to work in harmony with the factory components so there won’t be any troubleshooting after everything is installed. AEV also claims the FX370 kit was designed to balance daily usability with enhanced off-road capability. AEV doesn’t just see this as an option for off-road toys; it claims the FX370 kit is perfect for commercial users and everyday towing and hauling as well.

So what do you get? The kit is built around 37-inch BFGoodrich All-Terrain T/A KO3 tires, hence the “370” in “FX370.” They’re mounted on 18-inch wheels from AEV’s catalog, and aren’t simply bolted on. AEV provides a tire-clearance kit, recalibrates the speedometer, and swaps out the door-jamb sticker with a new one denoting the bigger tires and showing pressure and payload information just like it would for factory-fitted tires.
The kit also includes a four-inch suspension lift with AEV-tuned Bilstein dampers that the company claims preserve on-road ride quality. A stamped-steel front bumper can house a winch and has built-in recovery points, while a “high-clearance” rear bumper improves the departure angle and features its own recovery points. A graphics package with matte black stripes running across the doors and bed sides doesn’t do anything for off-road capability or functionality, but it certainly looks cool.

Since this kit starts at $19,999, it’s not exactly a budget option. That’s doubly true for enthusiast owners who might have the cash flow to buy a pile of parts piecemeal, but not to plunk down for everything at once. That being said, this more thoroughly engineered setup eliminates guesswork that could lead to additional, unintended costs down the road. It’s also quicker to buy the kit and install everything in one go, improving uptime for the commercial users AEV is also targeting.
If you don’t already have a truck to modify, it would be even simpler to head to the dealer and get a Super Duty Tremor. At the time of writing, the Tremor package itself costs $4,450, but depending on the trim level you add it to, there may be additional required options that raise the price. The net cost for upgrading an XLT—the lowest trim available with the Tremor package—is $13,575 once you factor in the cost of four-wheel drive and the mandatory crew cab. Tremors also ride on 35s, not 37s. And if the bigger tire still isn’t enough, AEV also offers a kit that puts the Super Duty on 40s.
