A 4 x 4 conversion company can take almost any van from paved suburban streets to winding off-road adventures. Popular with van-lifers and those who love to experience life on the open road, converting a 2-wheel-drive van or RV into a 4×4 combines the best of living in a spacious and comfortable vehicle with enjoying terrain that most 2x4s struggle to tackle.
While Do It Yourself 4×4 conversion kits are available, they require a decent amount of expertise to correctly assemble, and if you don’t have the know-how it can be a struggle to keep up with the maintenance of a DIY converted 4×4 vehicle over the long term.
Since not all of us have the niche understanding of 4×4 van conversions, the go-to option is often to turn to a company that specializes in converting vans into offroad vehicles. There are companies across North America that offer conversions – but it can be difficult to know which is going to deliver the results you want.
Here are 10 North American-based 4×4 van conversion companies that are worth checking out, and the best ways to decide who to trust with your vehicle conversion.

Choosing a 4×4 Conversion Company
Price is a big deciding factor – some companies reduce the cost to their customer by sourcing recycled or pre-owned parts, but this can make finding replacements a challenge. Alternatively, others rely on factory-produced parts from your van’s manufacturer which can hike up the cost but provide a little more peace of mind.
Location will also impact a customer’s decision. There are a limited number of trusted 4×4 converters in North America and there might not be a huge range of options for garages and dealerships in your area. Luckily, most companies offer domestic shipping at a price.
Whether you already have your van or want to buy a particular model will influence your decision. Not every converting company will work on every model – in fact, most of them pick just a few vehicles to focus their expertise on.
Researching and contacting a company that offers 4×4 conversions is the best way to find out if they can service your vehicle.
What is the Best Van to convert to a 4×4?
Ford vehicles are widely regarded by those experienced in conversion as the best vans to convert to a 4×4 vehicle, with both the Ford Transit and the E-series being popular choices.
The Ford Transit has a high roof, a powerful engine, and good fuel economy (about 16 miles per gallon). Production on the E-series has been discontinued, so you will only be able to purchase pre-owned vehicles but it is essentially the predecessor to the Transit.
Most 4×4 conversion companies and garages work on Ford vehicles such as the Transit or E-series – making replacement parts and experts willing to work on your conversion easy to find.
Can you Convert a 2×4 to a 4×4?
Converting a 2×4 to a 4×4 is possible, but it does require some research and expertise. Parts like the front suspension, a transfer case, and an engagement system need to be purchased which can be pricey – but then there’s always the option of seeking out recycled or preowned parts which significantly reduces the cost.
Many 4×4 conversion companies also offer kits if you want to do your own conversion, but this does often leave you with a lack of support in terms of troubleshooting down the line. Most companies also offer decent warranties with their conversions but not their kits, and some vehicle modifications can void the original manufacturer’s warranty.
The consensus on most forums seems to suggest that it is only worth converting a 2×4 if the model cannot already be purchased as a 4×4 vehicle, at least from a financial perspective.
Can a RAM ProMaster be converted to a 4×4?
A RAM ProMaster doesn’t tend to be a popular choice because its 4×4 conversion is generally a more complicated process than when starting with another vehicle (such as a Sprinter van or Ford Transit/E-series).
The RAM ProMaster doesn’t have the ideal frame, and therefore foundation, for a 4×4 conversion. It is a front-wheel-drive with a low floor, which is generally less compatible with 4-wheel-drive mechanics as it leaves limited room for a transfer case and driveshaft under the vehicle.
Not very many trusted converters work on Dodge vans, so if you’re set on a conversion you might have to do the handiwork yourself – this being said, if you have the funds, time (patience!), and knowledge you can do some major work and convert the ProMaster to a 4×4.
When looking for a 4×4 conversion company, Quigley stands out to me based on their testimonials. They work on many different van models and makes which expands their customer base, but still manage to provide quality support to their customers even after a van has left the garage.
I like the idea of using a converting company that sources all of their parts from the original manufacturer where possible – it just adds to my peace of mind knowing that parts are easily replaceable and under warranty, and this is something Quigley takes pride in offering.
Converting a two-wheel-drive vehicle to give it 4-wheel-drive capabilities is a good way to combine the comfort of living in a van or RV with the thrill of offroading and exploring off the beaten track.
Finding the right company to convert your vehicle can be a challenging task if you’re not sure what to look for, but with appropriate research, budgeting, and figuring out exactly which features you want your vehicle to have it is possible to build the vehicle of your dreams!
