Moving on to the rear

So the front is done: accutune custom valved extended travel fox 2.5s with a 500lb spring and dsc adjusters with jba uca's. Needless to say the ride is on point.
So now I need to get the back done. I will send the rears to accutune for their valving, thats the only certain so far. Ideally I'd like a total of 1.5-1.75" of lift with a great ride and hopefully some extra travel to compliment the front.
Right now I have a coach builder +2 shackles with some factory leaf springs that have seen better days. I'm assuming I dont have the true lift from the shackle due to the leafs flattening out. I like the idea of the deaver f85 mini pack but not sure I will benefit from it due to the leafs already being flat. Will the mini pack help rearch the springs? If I go with the mini pack and the factory leaf what shackle should I use that will net between 0" and .25" and be better than stock?
There is always the +3 shackle but that wo t help improve my ride, which isn't bad right now, but I'd like the best I can get.
Lest hear your best riding options for the rear with 1.5"-1.75" of lift.
Thanks

 

replacement leafs from alcan or deaver, they can build what you want. Or Dobinsons or OME for about 2 inch lifted springs, decent and cost much less.

If your leafs are bad/flat, add a leaf or shackle will not help you.

 

Alcan, deaver or icon rxt

 

This is what I was worried about. I'm going to call a local spring place and see if they can reach them for me. Maybe even add some progressive leafs.
If not then I guess I'm looking into new full packs.

 

Icon, wheelers sell expansion packs. Those yield 1.5"

 

If I can rearch then I will definitely do the expansion pack.
Icon over deaver?
