Im thinking about putting f250 springs on my 97 XLT 4x4 f150 so it'll stop sagging when i have to haul my trailer or stuff for work. Will leafs from a f250 bolt right under? If so, does the year matter or is all years the same length? I wont have to drill new holes or make new brackets will I? and will putting f250 springs lift the rear of my truck at all? Ive seen discussions about this in the past but I don't understand all of it so please any feedback is appreciated thanks!

Why not just get some air bags?

Depends on your definition of "F-250".


In '97 model year, Ford had both an F-250 LD (light duty) and an F-250 HD (heavy duty). The F-250 LD was basically an F-150 with heavier-duty wheels, tires, and suspension. The F-250 LD had the same cab as the F-150, while the F-250 HD had the much tougher cab and chassis of a real three quarter ton truck.


The rear springs for an F-250 LD will fit fine on your F-150 = same length and width, but more weight capacity to increase GVWR from your max of 6,250 to an F-250 LD max of 7,700.


F-250 HD springs won't fit. They are shorter and wider, so don't even think about those.


But the F-250 LD rear springs should be a good mod to increase the weight capacity of your rear suspension.

That is an awesome answer sir thank you so much! My only remaining question then Is will it lift the rear end higher than it currently is?

Probably not much, if at all. Those F250 LD's smokeywren spoke of (later known as the F150 w/ 7700 payload package) didn't sit noticeably higher than the Regular F150. maybe a touch, but not noticeable.
Why not just install an add-a-leaf, or even bring it to a spring shop, and throw an additional leaf in. Unless you can find a set of 7700lb springs cheap, that would be the way I would go.

F250 Ld springs have 4 leafs instead of three. New oem ones may be hard to find and expensive.

New OEM parts for a '97 are probably no longer available. Ford stops making them when the vehicle is about 10 years old. Your '97 is closer to 18 years old.

They still sell them at http://www.sdtrucksprings.com/leaf-s...-suv/ford/f250 does it matter what year or just That they're 2 1/2" wide?

raisin

Springs for that year are listed at 2 1/4" and 2 1/2" make sure which yours are.

I have to go back to the first question. Why not just install air bags? They are easily adjustable for the desired load and have no negative impact on ride quality when deflated. Or do you actually need to replace your springs due to fatigue, breakage etc.?
