Where do I find...............
1" lift shackles. I have a 4x2 screw. I put a 2" AS on, it's a 1 5/8" spacer, and the front is now 1/2" taller than the rear. I don't want to mess with the 4x4 blocks, I just want to get some 1" lift shackles and I can't seem to find any, and I've searched! Anyone have suggestions?

I was thinking that, but I've heard it both ways, like some say it'll settle and some say it won't. I know this when I have the back loaded with vacation goodies I don't want to sag even more. I also will be pulling my father-in-law's boat periodically.
I've had it on since sunday and it's getting aligned at ford tomorrow, as well as the brake tsb, spark knock tsb and a recurrent vibe issue.
Just found some on the web, from DJM. It says they're 1" lifting shackles. I'm going to call them tomorrow and see if they'll work.
Do you guys think the stock shocks will do with a lift shackle?

The reason you can't find lift shackles is because they don't make them for our trucks(that I know of). You would not want them anyway, they can put your rear suspension in a bind and possibly break something.
With an overhung leaf spring like we have, the shackle end of the spring is over top of the shackle bracket on the frame, and to lift it, you would need a shorter shackle and that is a no-no.
A leaf spring needs room to move laterally during compression, thats why we have shackles in the first place. When a leaf compresses, it flattens out, and when they flatten out, they get longer,hence the need for shackles, to allow for lateral movement.
When you add shorter shackles, you reduce the amount of available lateral movement, and if you go far enough, you can actually put your suspension in a bind on compression.
You would be better off using an Add-A-Leaf or adding a block to get the lift you want.

Oh yeah, What size lift do they come in?

OK, so an AAL is what I'd need. Can't tell I'm new to the lift thing can you? Can the DIYer manage to put on the AAL? I'm clueless to how this is done, I guess I need to do a search. I did the AS in like an hour, without pneumatic tools, just hand tools. If it can be done, I think I can handle it. What do you guys think?
P.S. if your good, you can do it with main leafs still in the truck

I may have to get my hands dirty soon.
