I just swapped out my 2" spacers for 3" coils and cut the spacers in 1/2, so I guess I have 4" in the front and around the same with a bastard pack and shackles in the rear. I need to redrill the track as my driver side tire sticks out, but the LCAs seem fine. Is it only when wheeling /flexing that longer LCAs are actaully needed?
