I have a 6.5in loft on my xj and I’m replacing the leafs in the rear and I’m wondering what the best setup is. Should I run 4.5 springs, shackle relocation bracket, and a drop shack or should I run 6.5 in leafs with stock shackle? Or is there someway to run 5.5in leafs with the shackle relocation? Also Im looking for the best setup for rock crawling.
