F-250 into F-350

I want to make my F-250 CCSB into an F-350. What differences are there between the 2? I always thought that it was just the rear suspension. But I havnt looked into this before so there may be a good bit more than that. I know the 250 doesnt have enough suspension to hold up some of the loads I put on her.

My thoughts are to put a set of 350 springs in the rear and air bags and be good to go All that assuming that the springs will bolt on right on lol.

Cant afford another truck so this was my idea lol.

So any info yall have is appreciated!! Thanks Guys

some people say only the springs are different.
Some say the axle is also different...


I believe it is just the springs by looking at all of them.


I (and many others) have thought about this but decided against is because is a LEO pulls you over for being over weight they will look at your door tag anyways and if it is more then you are "rated" for then you will be getting a fine...

Even if you put F350 or F650 springs in there they go by the door tag ONLY!!!


Not worth the trouble IMO

But I guess if your just using it to haul tools and whatnot in the bed or concrete blocks you wouldn't get hassled too much


Might be worth it just for the "peace of mind" of having stronger suspension

You can swap out the blocks in the rear axle, that's the only real difference. I don't think there is any difference in the springs. What I would recommend is a F350 set of blocks, and install a set of air bags.

The reason the F250 is offered is that is typically a sub-10,000# GVWR truck. For the purposes of registration/insurance its typically cheaper to own the F250 vise the F350. If you violate the axle, or GVWR on the door panel, you will find yourself in trouble if you are caught overweight at a scale, or after an accident.

I heard that they are going by door and VIN. I know that you used to could register it for more weight. I am not sure that's the case these days. That wasnt but 3 yrs ago or so. I could be totally wrong about that though. I know I want to buy a camper and they can be anywhere around 16k to 18k pretty easy. I haul flat bed trailers from time to time with equipment on them...skid steerer and what not. I may have to just buy another one, but I know right now the bank wouldnt loan me the money

The 250 and 350 single rear wheel models, both run the same rear end (a sterling 10.5, the dual rear wheel 350s run a dana 80 and the 450s run a dana 110). The main leaf springs are the same as well. The difference is the presence of factory overloads (350's have them, 250's don't) and the size of the factory block (the 350 block is a little taller). If your planning on running airbags anyway (which is a great idea), then I wouldn't worry about doing anything else besides adding the airbags. You won't need the overload springs with the airbags, nor will you need the taller block as both of those functions will be done by the airbags.

I had read somewhere that the airbags were mainly to help support the load not to increase the load rating of your truck. Suspension is my weak link in the gear head world. I do not know much about it or how it all works. I want to run a 2.5 leveling kit with a 350 block in the back and want the truck to handle the weight of a 350 and hopefully with the bags ride level. That's what I am trying to achieve. So I am all ears to you guys that know suspension

Thanks for all the info guys!

I thought they had different braking systems as well. I also dont understand the weight thing. In NC I can register my truck for as much weight as I want. My tags right now are for 13K lbs but my door sticker says 10K

it's been shown in the Ford builders guide(see link) that the 350 has a thicker frame /different splines on the sterling axle and the taller block/u-bolts and different shocks . oh and the badge IIRC ?

I never believed the frame thickness difference because it was so miniscule it seemed stupid and have never been able to verify the axle spline count also seems useless
