I am currently running a 3in Zone lift with a full rear leaf pack, with 33in tires. the shackle angle is what is killing me. I would like to get the HD no lift shackle relocation, after a little research apparently this requires a lift shackle or your shorter shackle becomes a bump stop on the relocation box. the question is how can I build this with out lifting my back end up? my current ideas are.
1. grab a 1.5in shackle and a 1in block, then swap out my lift springs for stock springs.
2. build a s10/ XJ bastard pack and use a 1in extend shackle.
3. upgrade to 35's and bump stop accordingly then hope that the bump stops not the shackle limit my up-travel.
I am more then willing to listen to/ try a different idea id just like to keep it low.

I ran into the same issue with my 3" Zone full leafs. I installed the HD no lift brackets and tried using some IRO adjustable shackles (0-.75 lift) but they wouldn't fit in the relocation brackets. So I tried my RC shackles and the only way they would fit was to put them in the lower holes on the HD brackets which netted me @ 4.5" in the rear. So I compensated by adding a .75 spacer to the front coils.
In hindsight I probably should have left my crown HD leafs in the rear, added the relocation brackets and a extended shackle and would have most likely netted me closer to a true 3" in the rear with a good shackle angle.
All in all I'm happy with the 4.5" lift. I tried several different approaches but never could get a true 3" in the rear with the Zone leaf packs and a correct shackle angle.

Excellent point, if you move forward the mounting point say 4" with a stock shackle, we'll say this is 4" eye to eye, idk for sure, then you could run a 5.65" shackle without gaining lift, and have a 45° angle. Assuming your current angle is 90°

The height netted by the shackles is not directly related to the length of the shackle. The angle of the shackle and the length of it factor together. Basically working with a triangle, pythagorean theorem. The current shackle is adding it's length to the height of the lift due to being at 90 degrees. With the new shackle at a 45 degree angle, it will only add around 60% of it's length to the lift height. SO, if the new shackle is only around 40% longer than the existing, it shouldn't add any lift. That's the theory, YMMV.

I was as well till i did some more resurch, i have found 3 threads with similar story's. the issue is not the brackets they are no lift but to clear them you have to put on a extended shackle that nets you....extra lift in most cases.
Thank you Bad Idea ill call HD and see what the shortest length they recommends running. then break out the old geometry text book.

I like the idea of pulling one leaf.
