Im thinkin bout adding maybe an inch of shackle lift. Would this be ok with the 2.5in pro comp? Also should I do straight or boomerang? I thought I read somewhere that the boomerangs on the front help protect against spring inversion.

Thanks
 

1" of shackle lift is ok. You might end up needing a few castor shims, but that is not a big deal. Yes, is can help with spring inversion if they are installed correctly. That being with the "V" pointing towards the center of the vehicle. I run boomerangs on mine, and it seemed to help the flex. But that may be the placebo effect. I say go for it. 1" of shackle is not a big deal. BIG shackle lifts are bad.
 

Boomerangs, they help prevent spring inversion in the front, been there done that. And in the rear they allow more spring compression before the shackle hits the frame crossmember.
