Jefe, my leaves are also very fatigued. With the Warrior shackles and an addaleaf, I still had lost all lift.
I pulled the leafs off of a mid-80's F150. The second-longest spring in the F150 pack fits under my main leaf perfectly just short of the eyelets and supports it again back to the original curve and height. I also removed my little addaleaf and used the short F150 leaf in place of my original short leaf.
Yes, it rides like a truck. But I got my lift back and some badly-needed assistance for my main leaf, all for $50.
