Hi All - I recent installed boomerang shackles that give an extra 1.5 inches of lift. My question is, do I need to change my leaf springs to a larger size due to this, or can I keep them? I allready have springs on there (Rubicon Express) for a 4 inch lift, which is what I have. Should I keep these on or do I need a 5 or 6 inch leaf now?
