OK, has anybody done this? I have some leaf springs out of a 93 F350 Dually. How much lift would this give me? How bad would this effect the ride? Any and all input is appreciated.

 

I've put F350 springs in an F250. I had to get different driveshafts, shocks, and the stock Ubolts were JUST long enough. The ride even from the 3/4 ton to the 1 ton suspension really stiffened up noticeably. Im guessing that you may end up with about 6 inches of lift maybe? I got 4 inches of lift on a 3/4 ton so it must be a hair more.

 

If you have false teeth, you better stock up on Polygrip!!!!!!!

How about this?





But in all seriousness, don't forget putting a 1 ton spring pack, sure it might give you more loading capacity, but then again not really. You still have the rather weak half ton semi-floating 8.8" axle witch is no bullet proof axle...

Plus, F250/350 springs are an inch wider.


I drove a long time ago a boxless F350 with a bigger leaf pack than my motorhome in that pic, and I swear I ran over a dime and can tell what date was on it!

 

are you just looking for lift? if so you might want to look into a shackle flip to avoid an overly stiff suspension. sell your tonners on craigslist to fund the parts and be money ahead!

 

Shackle flip isn't that to lower?

 

3/4 and 1 ton springs are the same width as 4x4 1/2 ton springs.

 

It should work fine, as mentioned before. A bit stiff
Also won't increase load capacity because other components still haf ton
Block kits are cheap if you just want lift

 

Yes but with block kits you can get some serious axle wrap. I know from experience.

 

I did the shackle flip and got about 2 1/2 inches. I still need another 3 inches. I'm not worried about load capacity. I have some blocks that I am trying to avoid using.

 

Hate to brake it to you but 3/4 and 1 ton springs are the SAME THING. So you either didnt have 3/4 springs in your truck or you didnt put 1 ton springs in.

The only difference between the rear suspension of a f250 and F350 is the 2.5" block on a F250 and 4" block on a f350. Both a 5 leaf springs
THAT IS IT. NOTHING ELSE

And to the OP, unless you want to add weight carrying capacity to your F150 you would be foolish to put 350 spring in. Ditch you F150 block(2") and put in a F350 block(4")

 

When I had my 95, I went to the junkyard and got some springs out of an F-250. They had 6 leaves in each side, mine had 5. Turns out I couldn't get the bolts out of the ends, so I dissected the leaf packs and added 2 leaves on each side. That gave me about 2.5" of lift. It rode like a hay wagon, but I filled the bed up completely with black dirt and it sat perfectly level.

I also had front coils out of an E-350 van and a 3" body lift. I had 35" tires on it.

 

Just put an extra leaf in it, putting 350 springs wont work allt o well-they are wider.

F150 uses 2.5" springs, F250/350 uses 3" wide springs.

 

No actually 4X4 F150s use 3" springs. Only the 2wd F150s have 2.5" springs.

 

Diesel_Brad- Thank you once again. You really know your stuff.

Thanks everyone for the help.
