Quadvan.com??????

I was kind of under the impression there were only two (major) 4x4 van conversions out there. Quigley and Sportsmobile. Now I run accross Quadvan?! Has anyone heard of them???? They're out of Portland, OR and their web site is still incomplete....some sections still under construction.

I found them doing a search on Ford diesel vans on Ebay. It popped up something they were selling. What got me interested was the fact they will convert not just NEW, but older 'used' vans also!!!

I've been to their shop. It's immaculate. When I was there, they had a couple Class A motorhomes out back. I asked what those were for, and it turns out they were SalemKroger conversions that were sent to QuadVan for some re-work.

I plan on having my van done at QuadVan within the next 2 or 3 months, once I find out what their availability is. Most of the 4x4 vans I see in the NW are QuadVan rigs. On Mt. Hood, 4x4 outnumber 2wd about 2 to 1 it seems.

QuadVan and SalemKroger both use the newer F-series setup, which I think is superior to the Quigley setup. The Ford style setup is not prone to Death Wobble, and is 100% serviceable at all Ford dealer.

Do you happen to know how much their conversion runs? They listed on the Ebay ad that they can do 'pre-owned', but I'm wondering how far back they go.... I'm guessing that my 'beast' is WAY too old for a conversion then.

I didn't realize that there were more then the two. Four companies that convert! I'd prob. go for the QuadVan since it's 'local'- Portland is only three hours away from me.

Everybody thinks their 4x4 conversion is better, its a marketing thing. Quadvan claims to use the most factory Ford parts and I believe it costs $12K for them to convert a van. Sportsmobile is more of a hard core offroad conversion using leaf springs, a Dynatrac axle, and Atlas transfer case. Think its $16K and they really only do new vans. Salem Kroger will build whatever you want. Quigley is the only one certified by Ford (new vans are drop shipped to them for conversion) and can be worked on by any dealer. Quigley uses the complete axle and transfer case from a F350, but makes the radius arms, some brackets, and modifies the front disc rotors so the van ABS will work.

Any 4x4 with a coil spring front suspension can get death wobble. Quigley installs dual steering stabilizers to control it.

Or you could go with a Ujointclothing Bracket Kit and either install it yourself or have a local offroad company do the work. This way you can have it built the way you want. Untitled Document

Dang! Maybe you should not have shown that link to me. But my van is a 1990! Says it's for a '92.

If you contact Chris he'll know if it will work for the 90's. He's a good guy and is very willing to help. (Chris owns Ujointclothing and is also a member on this forum)

Thanks. I see in your sig. that you did that conversion. Mind if I ask how much you put into it when it was all done and said?

I think I am the only Quadvan owner who regularly trolls this forum so here is my take:

Cost is $13k.

I waffled between Quadvan and Quigley for some time. I liked Quadvan, because I was able to get a brand new conversion on my Luddite 7.3L. I would have had to buy a used Quigley to get the same.

At the time the Quadvan had a better design as well, using the 2005 F-350 front axle assembly/brakes/locating arms. It gave a tighter turning circle than a factory E-350 and much better brakes.

Since 2007, Quigley has started using what appears to be the same front end. I don't think there is an appreciable difference in the two designs anymore. But if you like the 7.3L and want the new front end, you won't find a Quigley equipped like that.

In terms of cost, a Quigley "only" runs about $10.5k, but they charge $800 for alloy wheels and $700 for 4 Bilstein shocks. My Quadvan has 18" factory alloys and 6 Bilsteins. So it's still about $1000 more, but in the ballpark.

I'm really happy with the work they did. The van has no vibrations even at 95mph (on a closed track of course). Two complaints: 1.) The corrosion resistance of their parts does not match that of the factory frame. A few more years and everything under the van will be rust colored though.
2.) They offer a 2" and 4" conversion. I went with a 2" for fuel economy and a lower c.g., but it simply does not offer the suspension travel that I need. I would definitely go with a 4" conversion.

btw, their website has been "under construction" for years.

I ended up doing a lot of things that I did not need to do. Until this project the most I had ever done on a car for the past 25 years was change the oil. I decided I wanted to know how to do everything I could so I bought a good low mileage axle for $900 which could have run just the way it was. I decided to put in new u-joints, ball joints, and 4.10 gears. This added to my cost when it didn't really need to but heres what you have to spend.

$550 Bracket Kit
$900 Dana 60 Axle
$600 New custom leaf springs (2" lift and 2" axle push (I should have only gone 1")
$120 Stainless Steel Brake lines
$250 New Rancho Shocks
$250 NP271 (NV271) Transfer Case
$200 New Output shaft and Housing For Transmission
$360 New Rims because of new bolt pattern
$200 Wheel Spacers for the Rear Axle
$285 Shorten Gas Tank
$30 3.5" lift Block for rear
$80 All new U-bolts for axles
$500 New gears for rear axle
$??? New Drive Shafts (Haven't Bought Yet)

$4275 Total Cost Without Driveshaft or Transmission Costs which will probably run another $1000

Thank you beaker and Clark2. As a few four wheeling people I know, it's not cheap. One built his own 4x4 (he welds for a living) and the other works for an auto parts store..... I suppose between the two, I could get it done. No 'toy' is ever 'done'

Oh, if you want to see a pick of the van I bought, the pics the seller put up on Ebay are in my pic section (I guess click on that little link below the user name that lists how many pics I have). I've been told it's a fairly 'high' looking 1 ton- some actually asked if it was 4x4.

If I did convert, I'd prob. like to keep the same hight as it is now. Would a F350 axle from 1990 work in the conversion? I'd like to retain the same type of wheel pattern/type.

I haven't searched on the ujointclothing kit and I'm sure someone posted their conversion (if you didn't do it Clark2). I kind of like to do a 4x4, but $$$ is an issue. As of right now, I am thinking of a Hypermax turbo for my van. Unfortunately, I have WAY too many projects going here and there in other areas right now..... (gotta get some things done first).

I have an E-350 Quadravan 4x4 conversion, with coil springs and radius arms. My Quadravan was Ford ship thru approved, too.

In 1979.

Pathfinder Equipment Company was the first ship through approved 4x4 van conversion company, having begun 40 years ago. Pathfinder converted not only Ford Quadravan, but made the Chevy K Vans and the Dodge Ramchargers, until Dick Long closed the company in 1992, coinciding with when Ford changed body styles to more or less the current sheetmetal (ignoring front fender, grille, and hood changes).

Since the body style change, Quigley has been the dominant producer of ship through 4x4 conversions for utility companies, ambulance and rescue, as well as recreationalists that prefer conversion vans like Sportsmobiles. But in the 70's and 80's, the predominant player converting Ford vans with Ford's approval was Pathfinder Equipment's Quadravan.

So when I saw this thread on Quadvan, I clicked it just to make sure it wasn't a typo. Guess there's a new kid on the block now, using a deviation of an old well known name.

Quigley is the only 4x4 upfitter certified by Ford. Ford has to approve everything that goes into the conversion and Quigley maintains records of every part on every van, just like Ford does. You can order a Quigley conversion from any Ford dealer - the van will be shipped to Quigley, upfitted, and then shipped to the ordering dealer. Ford will warranty the 4x4 conversion. Any other 4x4 is only warranted by the company doing the conversion.

There are still more companies doing conversions. Advanced 4x4 in SLC comes to mind. Salem-Kroger is out of business. Most of the same people now work for Whitefeather conversions in Red Bluff.

HI, I know this is an older post but I just came across it. I am a 4x4 van converter out of Mass. Have been doing them for 15 plus yrs. I will have my website back up soon. I'm probably the only one willing to convert a pre '92 Ford van. I can do it with coil or leaf springs if you have a preference. I currently do the conversions with leaf springs and a total bolt on system. I am working on a coil spring conversion kit for the '92 to present vans and will let you know if it will work on the earlier ones.
Feel free to contact me and I'll send pics of my work if you're interested.
