I have a 2019 6.7 f250 4wd and I need a dually to pull my camper/toy hauler... What parts do I have to replace to convert the rear end of my f250 to a dually f350 rear end to get the same towing capacity as the f350? Thanks in advance for the help!

Oh boy. You just opened a can of worms with the sticker police on this site!

I believe one or two people have done a conversion here, so it can be done of course. Bare minimum you'll need the complete axle, springs, and probably the driveshaft. Good luck!

 

Does Ford still use bolt-on fenders or will the bed have to be replaced too?

 

I assume, trading in the 19 F250 for a dually is out of the question ?

 

As pointed out above, the sticker police will come out. Personally I ride the fence on this.

Your ratings won't change magically, if you go through with this it wouldn't be a bad idea to have it certified for the new weight.

Then it becomes a matter of how far you want to go with this - do you want to do it RIGHT or just add an extra set of tires back there?

To just add a second set of tires and springs, you're going to need a dually axle, wheels/tires, driveshaft you MIGHT be able to reuse (maybe), fenders, wiring for the lights, and maybe a programmer if you change gear ratios or tire size. If you get an axle you're going to want a COMPLETE axle including brakes because you may not be able to reuse your old ones. Then of course you'll need the 1-ton springs of whatever weight rating you're going for, the mounts should be the same but if the spring pack you choose has overloads you'll need the brackets for those to touch off against under load.

That's the bare minimum.

If you want to do it RIGHT you also need the flares for the front end, the factory hub extenders/brakes, and another set of wheels for the front (probably more components I'm forgetting), so you can just carry one spare instead of two - dually rims have a MAJOR offset compared to standard rims, so if you don't put a dually rim on the fronts as well you'll need a dually spare and a standard spare - not to mention it'll look odd if you leave the stock wheels up front but have dually wheels in the rear since they likely won't match.

It's a LOT of work to do it, it can be done (it used to be kinda popular to do back in the 80's and 90's), but if you can swing it, it would be a LOT simpler, easier, and faster to trade your current truck for a dually. You might even be able to break even on trade depending on your mileage/options and the mileage/options of a used dually. Just do your due diligence and inspect it pretty hard - there's some hotshot drivers out there pulling the instrument cluster out to avoid building miles (or were a couple years back).

 

Thanks guys! I appreciate the information!

better served to fine a used drw imho, but the above posts I think have captured it all.

that front end will need some major work if you want it too look and drive right.

when you consider it all, they are two options to me.

1. Find a junk yard drw you can bring back to life using your current truck as a donor.
2. buy a drw either used or new.

 

What are the scaled weights of the current configuration of the F-250 and the camper/toyhauler? How far over on the rear axle and payload are you currently?

 

It can be done but it's $$$$ to do it right and it doesn't change the GVWR/Payload/GAWR, etc.....Seven rims and tires, new rear axle and springs, front hubs/rotors and related bits, dually fenders and paint, etc. etc. Pretty hard vehicle to sell when the time comes too. I'd take the conversion money and apply it to buying a factory DRW truck.

The lightest toy hauler fifth wheel I have seen has a pin weight around 2k lbs. Most are in the 2500+ range even empty. There are very few diesel F250s that will support that payload.

He may have enough rear axle rating to handle it, maybe, depending on his configuration, which is arguably more important. I wouldn't count on it, and even if he does it's likely to be close to maxxed out.

That said, I would still argue a nice dually would be better served.

 

Just buy a new truck and be done.

 

Yeah, I get all of that and agree that his current truck is most likely outmatched by the TH. I was just curious where he is with the present combo and just how much more truck is called for. I’m currently within a month of taking delivery of a new 19K fiver and have already upgraded my modded Excursion to a new F-450 to be the tow rig.

 

If I were getting back into big heavy fifth wheels, you've picked the truck I'd own. Though supposedly the F350s seem to have comparable weight capabilities, but that tighter turning radius of the F450 is just the cat's meow.
