I have an '02 f250 PSD and I believe the rear springs are weak for my camper. I would like to know if rear springs from any 99 and up F350 would fit. With the camper the A code F250 rear springs are almost bottomed out. Would B or C code F350 rear springs fit and would they give the same ride height. I do not want to lift my truck any higher than it is. I have air bags on the rear and they worked great, but while I was driving home with the camper (just bought it) For some strange reason the bags deflated and I think I screwed one up. I tried filling them up at a gas station on the I-5 and .75 cents later they went up 2 inches then deflated. So I drove from Mt. Shasta up the I-5 to Portland then home. That 7.3 was great on the I-5 better than I could have imagined going over the passes.
I weighed the rear axel when I got home and it weighed 3030kg or 6666lbs. The A code springs are rated for 6,084lbs and the B code are 6,830lbs. Have I got my info correct?
So would the F350 springs fit and help solve my problem?

They'd bolt up, don't know about the ride height. You could also put a helper or overload spring on if it needs more help.

 

I was hoping they would, I changed the front ones when I bought the truck becaused the travel on the front was 1/2 in on one side and 3/4 in on the other side. Measured from the rubber bumperette to the axel. If the front were fatiged the rear must be with a load on also.
I will start looking for some F350 rear springs

$145 per side from direct ford parts. look for the thread in the past couple of days that is titled "ed at Y2K ford parts where are you" The dually springs(C codes) will also fit, but it will ride rough.

 

I'd fix the air bags, and get a set of overload springs. Even if you swap to the 350 springs, make sure you get the overloads.

 

99.9% of the time air bag deflation is due to an air line that has been damaged.

 

Thanks to all who responded.

These were brand new air bags , that I bought unopened off Craigslist so no retail reciept. They were only on the truck for 3 days

, then we left to go to Califorina to pick up the camper. Half way back they sometime they deflated, and I probably drove 200 miles or more like that. I will buy new bags and try it again ,but I still want to put the F350 springs on for the extra weight of the camper

 

I would chech the bags befor replacing the normally if the don't get a hole rbbed in them it is a line or fitting

 

I noticed I've got a broken leaf in the rear, right above the lift block. Are the 350 springs different from the single and dually trucks? I'd like to run the 350 springs.

 

I found a set of b-code springs thanks everyone
