'06 Superduty wheels to an '04 E350? - Diesel Forum

Will '06 Superduty wheels fit on an '04 E350? They are stock 17 wheels from an '06 F350. Will they work on my '04 E350?

thanks...

Unfortunately, No. lug spacing is different. SuperDuty is 8 on 170mm Vans are all 8 on 6.5 inches. There are spacers and lug adapters, but that's generally not a good idea.

And, the vans are lug-centric - that is the tapered lugs center the wheel. The pickups are hub-centric - a flange on the hub locates the wheel and the flat lugs simply hold the wheel against the hub.

Okay...thanks. I was hoping it would work.

Not for OEM wheels ... All OEM wheels are hub pilot centered just like the newer F-series flat washer fastening system. There is no such thing as an OEM lug-centric wheel for any of the major car/truck manufacturers and is not even in their terminology. Now some aftermarket wheel manufacturers open up the hub pilot so the same wheel can be used on more than one vehicle and are in essence "lug-centric". You can't do that with the flat washer system and might be one reason why Ford went to that system on the F-series trucks, but that is just a guess on my part.

The tapered lug nuts and or flat/washer system is basically what "fastening system" is used with the tapered system being a little more flexible on very precise torquing of the wheels.

Go to the "Little Secrets" and look under some of the Van specific or wheel sections and see what an actual wheel designer/engineer "Popeye" is his name says.

The '06 wheels also have much more backspacing. So simply redrilling things to fit will likely not work.

Larry, sorry about the Hub-centric/Lug-centric thing. I know better than that, but that is still the terminoligy used to differentiate flat vs. tapered lugs.

In 05 the backspacing changed. That is actually an advantage for vans. The new back spacing is 2" more than the van backspacing. If you use an adaptor of 1.5-2" thick the tread width will be very close to the original tread width for the van. The 05 up F-Series wheels are wider than the van wheels and you have be careful, especially with a sliding door van.

No problem, and since this is often the aftermarket thing one forgets that OEMs don't have that problem. When one reads a lot of the F-series wheel stuff for the 99+ SDs a lot mention this lug vs. hub centered stuff and often a vanner gets a negative view of what they call "lug-centric" being those with the tapered seats/nuts and then think their stock van has a less than ideal wheel system which is just not the case. The stock van wheel and fastening system is just about as good as the flat washer system, but I do understand the flat washer system fastening is a better system for extra heavy duty use.

Maybe a 2" front and 4" rear would be more ideal then?

It seems I hear people adding spacers on the E-vans, for stability and to match the front track width.

Go to this site, look at the wheels on these vans. Some if not all are '07 Superduty. Quigley is now using adapters for the rear of their vans to install SD wheels.

HeyBob · 03-17-2008, 03:20 AM

From the Quigley site:

Our standard installation consists of a Ford solid front axle with 4 wheel anti-lock brakes, coil spring front suspension, manual lock out hubs, 4x4 indicator light, Magna Gear transfer case, 5-FORD 17" steel wheels, 5-LT245/70R17E tires, rear wheel adapters, tire pressure monitoring system (TPMS), 4-center hub caps and 31 gallon fuel tank on all cargo vans and club wagons. The original 35 gallon tank is replaced with a smaller tank due to the space limitation after the installation of the 4x4 transfer case. This proven durable 4x4 system increases the height of your van on average 3.5". This increase in height gives you a better field of view while providing greater body clearance for those go anywhere, do anything adventures.

I've heard of people doing that also. I really don't believe it works. It doesn't matter how wide the axle is, the springs will still see the same load and the van will lean the same amount. A wider tread width will mean the van can lean over more before it tips over.

On my van - stock van wheels 4.5" backspacing (from memory??) 05 F350 wheels 6" backspacing with 2" adaptors and 2" wider wheels/tires the outer edge of the rear tire is even with the outer edge of the body. Just where I wanted it. No need for plastic fender flares.

On the rear I widened the outer edge of the tires by 3". 1" on each side from the wider tires and 0.5" each side from the adaptors. You can't get the adaptors much narrower than 1.5", and then the wheels are still wider. The stock van front is already pretty wide. Maybe on the front it would be a better idea to find another solution.

I agree - it won't affect how the springs work. I was only going from hearsay that the wider axle was a helpful low-impact modification.

There is a benefit, albeit small. Its a radial movement puzzle. The same tire squashing the same amount on a sideload of the same magnitude - but now spaced out further - is going to yield less lean of the sprung mass.

You can get the same net effect using tires with stiffer sidewalls.
