So I'm planning on picking up an 04-06 LJ soon. I just found out they come with a d44 with limited slip in the rear. So my question is my money better spent putting an arb air locker in the rear, or buying a high pinion Dana 30 for the front and put the locker in that one. Also while I have them open does it make sense to regear to 456 will it effect the limited slip in the rear if I decide to go the HP Dana 30 route? Thanks guys.
