With the shackles in front you get a lot of bump steer, in my case it was so bad it threw it into a death wobble. If the truck is going to see much pavement I suggest a rear shackle setup, but if its a trail only truck it really doesn't make any difference.

Here is mine

What are you trying to accomplish? A full blown crawler? Mild SAS build? How much lift? What size tires? Are you dead set on leaf springs or would coils be better for what you want to do?

I just copied these CLICK, then welded them to some 1/4" plate to mount them outboard of the frame, then welded some 1/4" gussets to the frame. My shackles are made out of 3/8" strap, and the holes are 4.5" on center.

For the front I used a piece of 2x4 1/4" wall tube for the cross member and some 3.5" OD 1/4" wall square tube to make the hangers. I made all my cuts with a 4.5" grinder.

I used Rancho 44150 springs with one medium length add-a-leaf, spring rate of 250lbs. If I remember right they are 4" lift rear jeep wrangler springs. They were laying around my dads shop and he said I could have them, so thats what I used . Without the add-a-leaf they were too soft and were almost flat at ride height. Over all my suspension is about 8" of lift.

I think your are a little ambitious to try and do a SAS in a weekend but if you plan right and have everything ready to go it might be possible. It took me 3 months(weekends only)to do mine, but mine fought me every step of the way.

A lot depends on your hangers and your shackle length and also the frame contours. Remember every inch of shackle length gives you 1/2" of lift.

I don't know how much help this is going to be with my truck being a Gen 1.

My choice was a total shot in the dark, but worked out almost perfect.
I would say 2" lift rear jeep wrangler springs with a medium add-a-leaf would put you in the ball park. The add-a-leaf is for additional stiffness rather then lift.
