Hello All, new here and this is my first post. Hope I am posting in the proper location.

I have a 2001 F350 V10 crew cab long bed that I primarily use for towing my boat. Well, Iam looking to sell my boat but still love the truck.

I am wanting to convert this in to something I have always wanted, a lowered dually.

I have many questions and am sure there is things I'm not even thinking of..

Will a dually bed (from what years) simply bolt on??

If I want the single "fat" rear wheel look on my dually can I keep the same rear axle and what would I need (spacers etc)?

Does anything need to be done to the front end for the proper dually style rim?

I am obviously not very knowledgeable so anything I may not be considering please feel free to advise.

 

What's a "single fat rear wheel look"? Do you want the tires to be so close together they look like one tire? If so, what do you think will happen when the experience any type of load (large bumps)? Sounds like a ridiculous idea that'll lead to catastrophe.

If your truck is a single rear wheel truck now, then you have a little work to do.
front wheels are easy, you need the wheel spacer to use the dually style wheels. You can find them on ebay.
As for the bed, if you have 8 foot bed, dually 8 footer should bolt right on.
I believe your rear springs might be different between the dual and single wheel truck,, usually a dually sits lower in the rear than a single wheel truck. If you are lowering you will be playing with rear suspension anyways. With dually springs it's probably 2-3 inches lower than single wheel springs.
as for the rear axle, it would probably be easiest to buy a dually rear axle complete and swap it in. Just try getting same gear ratio,, or plan on making ecu program change for speedo to work right. Depending on how drastically you change rear tire size you will be dealing with that anyhow.
then the tires, if by fat single,you mean super single vs 2 tires each side, you could probably skip the rear axle swap and just buy appropriate wheels and tires to get that look. If you like the real wide single rear tire you can most likely get wheels that fit your current rear axle which will save a good chunk of money. More money for other things! If you do axle swap, you have to buy axle, 4 wheels and tires, or super single setup, 2 fat a$$ wheels and tires. 😆

 

He’s talking about a super single style rear. Like a semi, instead of actual duals it’s a single tire that takes up the entire space of the duals. If your wanting to lower the truck I personally would go with the super single way in the rear. The only problem is your going to be running 2 different size tires and 2 different size wheels one size for the front and one for the rear. It does have a nice look with super single rears but for everything else the traditional duals would make more since.
that’s my input anyway do what you want it’s your truck. Enjoy the build either way, that’s what it’s all about

 

I agree, the super singles look nice on a lowered truck. I think if I was going that route myself I'd consider not doing dual style up front, just for ability to use 1 spare on any corner in event of tire trouble. But, as said,it is your truck so take our advice or suggestions as info and do what you will!

 

1. Yes, you need the wheel spacers for the front wheels to run dually wheels. They're not inexpensive but they're easy to find.
2. The box between an 8' SRW and an 8' DRW are identical. You just need the fenders and everything to attach them - this isn't GM where they had plastic boxes for their duallies.
3. 'Super Singles' don't exist for anything smaller than 22.5" wheels as far as I know. My FIL was looking for super singles for his F450 last year and they don't exist that he could find. Yes, there are rims and tires made that are wide enough to look like 'super singles' for this size truck but they won't have the payload rating of true duals. It doesn't sound like you're that worried about it but it's something to consider - you're going to lose payload.
4. The spring locations are the same between a SRW truck and a DRW truck, and the height difference is accounted for by blocks between the axle and spring, not the springs themselves.
5. There is a difference in the axle itself, it is narrower between the wheel mounting surfaces. As noted it's faster and cheaper to buy a dually axle with the right gearing and swap it in, HOWEVER if you go with one wide tire you can probably play with the backspacing to make it sit right on your current axle without swapping the axle.

Overall it sounds like a fun project, and if you're not worried about payload/towing your single wide rear tires would be the way to go. You'll spend a lot more in rims but you'll save quite a bit in the axle department, and by not buying a whole box but rather just the fenders you'll save quite a bit there too.

 

somebody like this will be of greater information

Is your truck 2wd if so I have the spacers and whatever you might need front end wise. Just converted 2wd dually to 4wd.

 

Get the dually rear fenders and front spacers.

I would run some 20 inch steel smoothie aftermarket rear inners up front and a custom wheel in the back.

Sounds like an straightforward project really. Ask on a sport truck forum.

 

Anyone know on the front axle, does ford have a dual wheel style hub with the offset for that style wheel, or is only the spacer used?
reason I ask, I have a f250 2wd, I'm converting rear to dual, already have the axle. Trying to decide if I want to stay normal wheel up front or go to dual style wheel.
either way i go I need to widen front wheel stance. I might just run the single wheel style and get a wheel with offset I want to push wheels out. I'll just have 2 different style wheels that way.

 

QUOTE
the spacer is built into the rotor not sure what exaçtly needs to be change but I'm assuming the spindle hub assembly and calipers. Someone more familiar will prob chime in. I have an entire 2wd front end from from a 99 2wd f350 minus rims n tires.

 

I can buy something along the lines of these spacers to run a dual rim up front, there are several spacers options OEM and aftermarket. My chassis is an 08. I don't mind running a spacer but I was trying to decide if I want to run a wide single style wheel, or adapt out to run the 22.5 truck wheel, in which case the concern is that I'd have 2 adapters to get to that wheel. I feel like that's inviting trouble stacking spacers but maybe it's not??
And to prevent people with concerns about fitting truck wheels under my truck, its not an f250 anymore. I'm using the f250 chassis for a build. superduty body and power plant is history. Body going on has more than enough room.

 

if your using a body other than the SD then you can use the single wheel axle, the 8 to 10 adapters and normal semi wheels, or the single with custom made / drilled wheels (like American Force) and no adapters. Who cares that the rear is 3" wider on each side

 

Yeah I'm not even concerned about rear width, I have a dually axle back there already.
I trying to get the front wheels out a ways further to fit my new fender width better. 3inch wider on each side would be pretty good. Maybe even a little more

 

The front the dually adapters is how its done from the factory. There is no DRW front axle, just an axle. I ran 315/85/22.5 on steel 8 to 10 adapters, alcoa alloys. Took them thru rough fields and off road all the time, never had an issue.
