Rear Spring Question

I have a 4 1/2" rubicon lift which is 3 1/2" springs and 1" shackels, the problem is the springs have less than 2" curve in them and my question is can I add 2" add on leaf from a Ford Ranger lift kit that we didn't use on my son's
truck?.

ranger leafs are longer but the AAL should work.

I just had to replace my Rusty 6.5 inch lift spring, due to properly breaking in the Heep, I replaced them with the Rubicon 4.5 inch lift springs with out even any blocks and it sits just right, a little highier in the rear to comensat for add weight of gear. I am also using the shackles from tera flex. The new leafs for both packs were only about 350.00. If I was you and if you were going to replace the leafs I would look for a militry wrap set up. They are much much stronger.

Thank you for the info and moving the thread, i didn't think about it when i posted.
