91 springs vs 99 vs 05 vs 08 rear leafs
 

So im running the 05 frane but it is bare-no springs .
Yard wants 75 a pop for 08 springs. I dont want to pay more than 100$ for a pair.
I hear that these are pretty soft (and look soft i see new SD squatting all the time ).
I like my 91 leafs-hardly touches the helper springs with 1000 pounds in the bed. i would need another pair as i still need my truck rolling while i build this roller.

Anyone know or have a link to ford f350 spring rates and lengths?

73-04 springs are one length.
05+ springs are another(longer)

and 08s are even longer than 05-07.
