Looking to do the next upgrtade to the XJ. Curently on 35's with an ARB in the front and the rear is a LSD. I am running a ford 8.8 rear and when I had the 4.56 gears put in I had them rebuilt the factory LSD that it came with. But now after wheeling it a few times I am not at all impressed with how the LSD performs so I am looking to upgrade. Tossing around the ideal of either a detroit locker or the DandC cage kit. Either way it will cost me about the same amount of money. I'm just looking for the best bang for my buck. And thought I would ask some of you all that have been around the block a few times. Thanks in advance for you input.
