    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.

    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!
