Converting to dually
Hey so I'm new to the forum, just bought myself a 1992 F250 7.3 idi super cab with a 8' Bed, currently running stock wheels, with heavy duty suspension (5 leafs I believe, and a 1-ton axle (This is all my just quickly eye-balling it, I haven't actually gotten under and poked around to much, it's my best guess as the GVW is raises) in the back.
And I'm curious about converting it into a dually, I'm curious what it would entail, simple or difficult conversion, I've heard of it being done before, I believe currently has a 1-ton axle on it, would I simply replace the bed, and stick dual wheels on the back of it, or is it more intricate than that, involving swapping gears, etc?
Any information would be appreciated. Thanks in advance.

There are various 'one-ton' axles. It depends on a couple things, when you talk about replacing the bed, would you go flat bed, or pickup box with dually fenders? The biggest issue is tire to spring clearance, a true dually axle is setup from factory with a longer hubface to hubface distance than your axle. A cab and chassis axle is same hub to hub, but the frame and spring to spring width is narrower. To properly do it on your truck, as close as factory as possible, would mean locating a rear axle from a factory dually, and swapping it into your truck.
The issue now becomes that you have two different style rims on front and rear, so two spares are necessary (assuming you carry spares). To convert the front to bud style wheels depends on whether you are 2 or 4wd.
As to whether you have to change gears, again, depends what ratio you have now, and whether you are 2 or 4wd, and what ratio you want when you are finished.

for the front you can go two ways.
4x4 dually hubs from a f350 dually (2wd dually hubs will not work.)
or you can use dually adapters like here:
Welcome - Arrowcraft :: Helping You Handle the Road for over 30 years!
each accomplishes the same thing.however,with the 4wd D60 dually hubs,also requires their brake rotors.
a little researching some part #'s showed me,the year (and don't ask me yrs now lol) hubs you find,will depend on if you can use your calipers or not too.
look into that one more yourself though.i think it was when i checked on 1987 D60 hubs i saw id need to swap calipers too.i guess it wasnt the hubs,but that years rotors,listed a different # caliper.-not 100% on that.
the full conversion is more than just looks,and only 1 spare (or like me- none lol.)
it cuts costs of tire rotations.
it is very good,especially with the D50 to be able to swap fronts/rears.
having the full conversion is a standard swap,with no need for remounts/rebalancing to/from dually/reg rims.
so its good to see you want the full conversion.it's worth it.
i went the easy way so i wouldn't have to mess with hubs/rotors.
well at the tire shop,i saw i had a crack in a rotor.so i had to mess with it all anyway lmao.the way it goes sometimes i guess lol.

That site is quite useful, and I'd actually be quite interested in doing the full conversion, only problem being, I live in BC, Canada, and they only do face-to-face transactions... lol.
