You’ve seen them on Instagram. Massive, snarling, six-wheeled monsters kicking up sand in the Dubai desert or prowling the streets of Miami. They look like something straight out of a post-apocalyptic film, but they’re wearing a familiar Blue Oval badge. People call them a Ford truck with 6 wheels, though if you walk into a local dealership and ask for one, the salesman is going to look at you like you’ve lost your mind.
Ford doesn’t actually build these. Not officially.
Basically, if you want a Raptor with an extra axle, you’re looking at the world of high-end aftermarket engineering. It’s a niche occupied by companies like Hennessey Performance and PaxPower. These aren't just "trucks with extra tires." They are complete re-engineering projects that cost more than a starter home in the Midwest.
The Hennessey VelociRaptor 6x6: The Truck That Started It All
When John Hennessey decided to take a Gen 2 Ford Raptor and add a third axle, people thought it was a publicity stunt. It wasn't. The VelociRaptor 6x6 became the gold standard for what a Ford truck with 6 wheels should be.
It’s a beast. Honestly, it’s hard to overstate how much presence this thing has. Hennessey takes a stock Raptor and stretches the frame to accommodate a fully functional, locking rear axle. We aren't talking about a "tag axle" that just hangs there for looks. This is a true 6x6 drive system. They also bump the 3.5L EcoBoost engine up to about 600 horsepower because, well, you’re pushing a lot of extra weight.
The price tag? Usually north of $350,000.
Think about that for a second. You could buy four or five standard F-150s for that price. But those five trucks won't get you the same "look at me" factor as a VelociRaptor. It’s about more than just the extra wheels; it’s about Fox Racing shocks, custom bumpers, and an interior that smells like expensive leather and ego.
PaxPower and the V8 Alternative
Some people hate the V6 in the Raptor. I get it. There’s something about a Ford truck with 6 wheels that just demands a V8 rumble. That is where PaxPower comes in.
PaxPower takes a different approach. They often start with a Ford F-150 chassis that already has a 5.0L V8 and then perform a "Raptor conversion" on it. They add the wide-body panels, the long-travel suspension, and, crucially, that extra axle.

- You get the V8 sound.
- It’s often slightly more "affordable" (if you can call a $200k+ truck affordable).
- The customization options are deeper.
The engineering behind a 6x6 conversion is actually pretty terrifying if you think about the physics. You have to manage the "scrub" of the rear tires. When a vehicle turns, the wheels move at different speeds. Adding a third axle means those rear four wheels are constantly fighting each other during tight maneuvers. If the geometry is off by even a fraction of an inch, you’ll chew through $500 off-road tires in a weekend.
The Engineering Nightmare Behind the Scenes
Most people think you just weld some metal to the frame and call it a day. Nope.
Converting a standard truck into a Ford truck with 6 wheels requires a massive amount of structural reinforcement. You’re essentially cutting the bed off, lengthening the frame rails with high-strength steel, and then figuring out how to get power to that final axle.
Most builders use a pass-through differential. This allows the driveshaft to power the middle axle and then continue on to the rear axle. It's complex. It adds a lot of heat. It adds a lot of maintenance points. If you’re the kind of person who gets stressed out by a check engine light, a custom 6x6 probably isn't for you.
Then there’s the suspension. You can’t just use off-the-shelf parts. Most 6x6 Fords use a custom-valved Fox or King shock setup to handle the unsprung weight of two extra wheels and all that extra metal.
Real-World Capability vs. Mall Crawling
Is a 6x6 actually better off-road?
The short answer is: sometimes.
In soft sand or deep mud, having a larger footprint is a massive advantage. It’s basically the "snowshoe" effect. You have more surface area, so you don't sink as easily. The traction is also insane. Imagine trying to climb a steep, rocky grade with four tires vs. six.
However, there’s a catch. These trucks are long. They have the turning radius of a cruise ship. If you’re on a tight Jeep trail in the woods of Pennsylvania, you’re going to get stuck. Not because you don't have traction, but because you literally cannot make the turn.

Honestly, most people buying a Ford truck with 6 wheels aren't taking them to Moab. They’re driving them to high-end restaurants in Vegas or showing them off at SEMA. And that’s fine. It’s automotive art.
Can You Buy a Factory Ford 6x6?
No. And you probably never will.
Ford is a mass-market manufacturer. The liability and fuel economy (CAFE) standards involved in selling a 6x6 vehicle are a nightmare. Mercedes-Benz did it with the G63 AMG 6x6, but that was a very limited, very expensive experiment.
The closest you can get from the factory is a Ford F-350 or F-450 "Dually."
Wait, isn't a dually a Ford truck with 6 wheels?
Technically, yes. But it’s not what people mean when they use that keyword. A dually has four wheels on one rear axle. It's built for towing heavy trailers, not for looking like a monster truck. A "true" 6x6 has three distinct axles.
Breaking Down the Costs
If you are serious about owning one of these, here is what the math usually looks like:
- Donor Truck: $70,000 - $90,000 (Raptor or high-trim F-150)
- The Conversion: $120,000 - $200,000
- Upgraded Power: $15,000 - $30,000
- Custom Paint/Interior: $10,000+
You are easily looking at a quarter-million dollars.

When you have a Ford truck with 6 wheels, everything costs 50% more. Six tires instead of four. More gear oil for the extra differential. More bushings to replace. Even finding a car wash that can fit a vehicle this long and wide is a struggle.
And don't even get me started on parking. You will be "that guy" who takes up four spots at the grocery store. It’s unavoidable.
But for the owners, none of that matters. The experience of driving a 6x6 is unlike anything else. You sit higher than almost everyone else on the road. The sheer mechanical presence of the vehicle is felt through the steering wheel. It feels unstoppable.
Future Trends: Electric 6x6?
With the Ford F-150 Lightning now on the roads, the question is: will we see an electric 6x6?
It’s actually easier to build. In an EV, you don't need a complex pass-through driveshaft. You could theoretically just put a third motor on the back axle. Several boutique EV shops are already playing with this idea. The weight would be astronomical, but the torque would be enough to pull a house off its foundation.
Actionable Steps for Potential Buyers
If you’ve got the budget and the garage space, here is how you actually go about getting one of these:
1. Research the Builder, Not the Truck
Since Ford doesn't make these, your warranty and support come from the shop that built it. Look at Hennessey, PaxPower, or Specialty Truck Creative. Check their history. Do they have a track record of the trucks actually holding up after 10,000 miles?
2. Decide on Your Engine Choice Early
If you want the Raptor's tech but hate the V6, you need to go with a builder that specializes in V8 swaps. Changing your mind halfway through the build will cost you tens of thousands of dollars.
3. Check Your Local Laws
Some states have weird laws about "multi-axle" passenger vehicles. Most of these are registered as modified light trucks, but it’s worth double-checking your DMV requirements before you drop $300k.
4. Consider the Resale Reality
These are highly personalized vehicles. While they hold value better than a base F-150, the market for a used 6x6 is very small. You aren't buying this as an investment; you're buying it because you want the baddest truck on the block.
The Ford truck with 6 wheels remains the ultimate statement of excess and engineering. Whether it’s practical is a silly question. It’s a 600-horsepower, six-wheeled middle finger to the mundane, and as long as there are enthusiasts with deep pockets, these beasts will continue to roam the streets.
