Dually Conversion
Hi there, I have 2000 F350 / 7.3 that I would like to convert to a dually. Im wondering if the brakes ( master cylinder and hydro boost) need to be up graded as well or if they are fine as they are ?

you also need spacers for the front to push the front wheels wider so they line up with the center line of the rear dual's.
becareful on how you do this.....if you swap rear ends...be advised that 04's and earlier fronts are 8X170s, 04 and earlier rears are also 8X170's but 05 and later rear duallys are 8X200.
ideally, you would want all the rims the same so you can rotate them easier.

You would however need two different spares.

On the dually you just rotate the rears left to right. I guess having dual aluminum the inner would corrode like crazy?

I think it has more to do with the fact you can't see that wheel so why waste fancy materials on it.....
The fronts are polished on the convex side whereas the rear is polished on the concave side. So if you flipped them they would just be crummy on the other side. I guess if you had all black steel wheels you may be able to rotate them normally.

normally, duallys come with steel inner rims even if the outer are alloy.
the reason for rotating rears inside to out is due to the inner tires wearing more than the outer tires due to the curve of road surfaces.....the inners carry more of the load on a curved surface.
and yes, the polish surfaces of the rear and front on alloys are opposite.

My dad had his 03 converted. The brakes were fine. He kept the front wheels stock. It looks different, but he didn't want to spend the extra on it. I don't believe that there are any consequences, other than not being able to rotate from front to back. He's driven it for 10 years now converted, and towed some fantastic loads.
The local Ford dealership converted the Sterling 10.5 from single to dual hubs, and the body shop did the bed work.
As far as what Speakerfritz shared, dad only drives 3,000-4,000 miles a year. We haven't seen any consequences to the tires.
