This isnt a new technique. They do shackles at both ends and links. The spring at that point is only supplying elevation and the links do the locating of the axle.

He has off-the-self springs. Every lift kit spring, particularly in the 4" range, is too short. Have yet to see one fit a YJ properly and they all suffer from the vertical shackle syndrome.

So all the engineered kits are wrong, and a few JF guys are right?

Got it.

I was. I knew it wasn't "new" technique, but had never seen it before. Moving the mount points won't inhibit the ability to mount "off the shelf" items, unless I did a shackle reversal with stock springs. That's how I see it, anyway.

No its an economics thing. They take the same springs and put a larger arch in them. This makes them shorter from eye to eye. There are some companies that dont even make a spring larger then 2.5." No matter how it happens a shackle that is completely or near vertical is wrong.

Well, I finally made time to take a pic of the new front shackle(s) position. Mount points moved back approx. 3/4˝.
Also, when the springs were taken off, there were signs of wear in several spots across the #2 leaf, so the shop added pads to each end.
Jeep rides "softer" now and has less bump steer symptoms. For now, this will do for me. incidentally, I finally scored a decent set of stock YJ springs, for an SOA conversion in the future. I don't know if this will require moving the mount points back to "home", but I'm okay with that. SOA isn't in immediate future plans.
