OK, so do you know your current gear ratio ? If you want to go to 4:10's and have 3:08's in there now you will need two new carriers, with your stock carriers you can go to 3:73's. Above that, new carriers are needed.
I have only glanced thru the ARB stuff and I'm not sure if they are carrier sized sensitive or not, I would poke around quadratecs web site and see what they say, they may have a fitment chart. I tend to stay with auburn in my XJ and Detroit in my TJ and now my ZJ, but those two are D35's, the XJ is an 8.25 and that carrier will fit ANY gear size they make from 3:07 up thru the 4:xx.
