Lifting with just leaf spring possible?
If some body can point to the correct thread that would be great other wise this is something i cant find much info on
am going to be lifting my truck i have a 1991 ford F250 supercab 4 Wheel drive my leaf springs front and rear are SHOT to hell and gone i was wondering if it was possible to just get bigger lift springs say 3'' and coils and the shock to match and if a small lift could be done that way with a suspension lift later on down the road?

If you want spring only lifts, companies like SkyJacker make lift springs for the front, but will usually include only blocks for the rear axle until you go over 6" of lift or so (not recommended with the TTB front suspension). You can also look at Deaver Springs to build you leaf packs both front and rear for any lift and ride style you would like.
More commonly, for the rear, you can easily gain 2" of lift by just getting an F350 lift block; it puts your block at 4" instead of the 2" block in your F250 as is. As for new springs, you can go with any F250 or F350 springs from 1980 all the way through 2006. The 1980-1997 are going to be a direct bolt in, while the 1999-2006 are going to require you to drill out the hanger hole for a metric bolt. Super Duty springs are designed to be a more progressive spring pack than what you currently have, so the ride will improve. However, the only way to know the rated capacity of the springs is to get the door code tag for the springs to keep the rating the same as what you currently have. You cannot know the model/rating of the spring unless you have the door tag rating.
For the front, you can go up to around 4" of lift before the TTB starts giving you issues with the lift (4" would put you level if you put in the 4" block in the rear). One of the more popular ways to do it is going to be with something like the SKY RSK (reverse shackle kit). It moves the swing shackle on the front springs from the front to the rear mount which greatly improves the ride quality. Inherent in doing this, you will gain around 2.5" of lift with larger lifts available.
Also possible, is a Dana 60 swap. Because of the design of the mono-beam axle, swapping in the Dana 60 with F350 leaf springs will net you around 2.5" of lift. You can then pair this with an RSK to get even more lift.
Edit: If swapping between the TTB and Dana 60, you need to also swap springs. The F250 springs are much stiffer than the F350 springs due to the way the TTB puts leverage on the spring pack. A TTB front end with F350 springs will sag worse than you have now, and a Dana 60 with F250 springs will ride like the front suspension is solid.
If you decide to go with a Dana 60 swap, you can swap to Super Duty springs when doing an RSK from either SKY or Precision Metal Fab. Both kits can be used to mount the longer Super Duty springs while also reversing the shackle location.
Super Duty springs both front and rear are a more progressive and softer riding spring pack than the 9th gen trucks came with; add an RSK to it and the ride will be night-and-day different.

Your best bet is going to be to do a lot of reading on coil over conversions (doesn't really matter what generation... the basic requirements are all the same).

First, no coil springs on a 4 wheel drive truck. It's leaf springs all the way around.

ya idk what i was thinking with the coils
Are your saying you cant go over 6'' with the TTB ? i was only looking to do like a 3''-4'' lift. so i guess that works outs
when i was looking at deaver's leaf spring i saw that the only had rear springs why couldn't you use them on the front too long perhaps
would deaver's in the rear and skyjackers up front work
or somthing along those lines
i dont really like leveling the truck i like the look of the rear sitting a 1'' or 2'' high then the front
i was thinking 3'' lift leafs up front and 4'' in the rear thoughts
and as far as blocks go i also hate them more then anything really idk why but the just look ugly too me. thats why i was thinking using the leaf spring to get the lift

If they get expensive though, it might be worth while looking into the SKY RSK and some junkyard springs; improved ride and a lift.

TJC, how did the ride with the SkyJacker leaf springs compare to stock?

You might have better luck if you go with a solid axle since welding shock mounts and swing arms mounts to the mono beam is going to be easier than trying to do the same with the TTB arms.

If you look at the pivot point on the passenger side of the truck, that is the driver's side wheel beam, the passenger side tire arm is mounted to the driver's side of the truck. This makes for very long arm independent suspension, but it's slightly flawed when used in the F250 with leaf springs. The coil spring F150 and smaller vehicles don't bind when the suspension flexes, but it does with the TTB.
For comparison, an F350 with the monobeam Dana 60.

With the factory installed leaf springs, it's debatable that the TTB rides better; TTB setups with coil springs definitely ride better, but yes, generally the TTB is going to provide a smoother ride than the solid axle. However, a Super Duty spring swap with an RSK will yield the best results for a "bolt in" swap. You can get a better ride with coil overs, air ride, and 4-links, but the benefit is minimal for the added complexity.
