Guys I know this is asked all the time but I just want to make sure about re-gearing my Jeep instead of creating problems. I am buying 4.56 gears for my 8.56 Chrysler rear and D 30 Front while upgrading to 32's from 31's. Is this ratio on spot for the tire size or should I go up to 33's? Also upgrading to this gear ratio are there any special precautions that I should be making regarding swapping out other stock parts such as casing and such?
Thanks in advance.

I was told that it fits 33's well. what size lift do you have? also youll need a new case for your front d30 unless you already have 3.73 gears in it which is doubtful especially if its stock. so yes youll need a new case up front but your good in the back.

im running with a 4.5 lift so I don't see any problems with clearance, just was wanting to make sure if I needed a new case or not. what cases woudl would you guys suggest. I am installed all of my own lifts on my past 3 jeeps but im a newbie when it comes to regearing. all help will be appreciated

Ive always heard to get an open case. you can search them on ebay. ill search around and see what else I can find. Im pretty new about gears as well but ive been getting help from some guys on here and im learning a lot

If you want to go with 33's I would cause your going with 4.56 gears but you might have to trim your fenders, If you already have 32's on the xj you will still be fine with those gears, then buy 33's when you wear the 32's out. But will have to get another case for the dana 30 ,and your 8.25 is good to go just like ZMAN32006 has said.g/l(Tire size is up to you ,you'll be fine with either 32's or 33's your choice)
