2WD Rear Leaf Spring ?
I am looking to replace the back springs on my 2WD. First & foremost is to replace the sagging factory springs and secondly to level the beast out. So after sifting through lots of threads, I'm somewhat at a loss for which option to use?:
1 - Replace with rear springs from 4x4 Excursion
2 - Replace with ? code or ? code from 2WD F250
3 - Use Pro Comp 4 Inch Rear Leaf Spring (I don't know how high factory springs, are so this would be a mystery to me)
Feedback?

I can't remember off the top of my head but I can definitely look tomorrow morning on the arches of the 2wd springs in relation to the super duty springs. I'll check in tomorrow morning if you are still in need.

So from what I am coming up with the 2wd and 4wd rear springs were pretty close to being the same (minor differences). Same weight capacity, same steel grading and same free arch. It looks like the 4wd had the rubber snubber while the 2wd did not.
If you are looking to level the rear out you could go with a B code or a C code.
The B code has a free arch of 7-7/8" while your stock spring has an arch of 5-5/8". The B code also has a few hundred lbs additional weight capacity over the stock Ex spring.
The C code has a free arch of 8-3/16" compared to the 5-5/8" stock spring. So the C code would give you the most height overall.
Another option is if you would want to do an Add A Leaf to your existing leaf spring.

Just curious what everyone's 2wd stock ride height is. Measuring from the ground to the bottom of the wheel well, centered over the center cap. Im 35 1/2 in the front and 36 1/4 in the rear. V10 with stock tire size.

For the rear, you could swap F250 springs however I think you'd need to stay with the stock Excursion block since the front would stay the same. I'm guessing a B spring would give you close to stock ride height where I C gave me +1.5-2". You could stay with the stock length Excursion U bolts also.

PS I should have said out of the 12 different springs I looked at, all give ~ the same ride height. I have no idea if there are more Ford springs out there or not.
