It depends. You may not need one at all. Put it all together then measure.
Also do a search uner my name and you find the same question.
Mine had a shackle reversal done so that changes things. Bottom line is you do not know until you put it together. It may be fine.

You can be pretty certain that a 2-2.5 degree shim up front will work great (it did for me).

As long as you are running stock length shackles, that is.

I have never put any shims in the rear, even now with the springs flipped.

Back when I ran leafs, I first used the 2" alum. shims on the front. They eventually failed & worked their way loose, causing my bottom spring mount hole to "egg". Didn't use any on the rear. I'd suggest steel shims, but it's been so long ago I forgot where I got 'em.

Anyone tell me what degree of shims to use with a 4" Skyjacker SUA lift?

Hodag
The 4" Skyjacker springs that I first put on my FJ40 didn't require any shims.

If I recall correctly Skyjacker advertised that shims were not needed for their 4" springs, it was one of the reasons I went with Skyjacker.

I forgot to add that I had a front suspension correction kit ,which provided additional 2 1/2" of lift & I was using the 2" Skyjacker springs. HTH!
