I was more wondering since OME doesnt recommend ANY shims, but know that adding some longer shackles will definitely require them. Didnt know who else is running this system, and what they found to alleviate this angle...
Also dont want to have to pay for an alignment shop twice to get it set.
Mine said with who I bought the shackles for. I remember Man-a-fre doing this for the 40 sereis shackles i bought and then southwest 4x4 did the same thing when I bought the ones for the 62 i have now.
Yea...ARB doesn't recommend shims for the standard 2 - 3" lift...but when I did mine I went for 2 degree shims based on recommendation at the time (10yrs ago?) by MAF. Taller shackle? Might consider more rotation.
