8.8 vs 8.25 install
I would like to regear and add an air locker to my 8.25. I've met with my diff guy and he can install a 4:56 8.8 axle w/an ARB and disks for the same as he would charge to regear and install ARB in the 8.25. He's built a bunch of 8.8's for xj swaps. Seems like a no brainer, is there any disadvantage to the 8.8? Am ready to install a SYE kit, so am getting a new CV DS anyway.

The only downside I could think of is less ground clearance. What size tires do you want to run?
My thinking is I want to run the biggest tires I can on stock axles for the most clearance under the diffs.

Yes I'm lazy right now, does anyone have dimensions comparing the two? Like the 9 3/4 ring gear on a Dana 60 vs a Chrysler 9 1/4 not being all that different?
I'm looking into the upgrade eventually, but not too soon to care to look it up. Axle shafts on a Dana 35 are barely bigger than the Dana 30.. Stats like that.

I can't pull up the specs but the 8.8 is a tiny bit stronger then the 8.25 is.If you want 35s both are good to go,But over that the 8.8 will take 37s if built right.

You just need to buy the swap stuff and figure out what you're going to do with the driveshaft. Weld the tubes and run it.

Pros for the 8.25 are its stronger than a 35, only need to carry one spare & its bolt in. You can lock it & beat the crap out of it on 33s & probably 35s. The worst thing about it is the drum brakes.

Adding an ARB to your 8.25" is the better option.
Factor in the cost of a 8.8, parts to complete the swap, welding, etc....
No brainer.
8.8 is a good axle but the diff is pretty big, so keep that in mind. It's going to dig a lot of ditches.

On 35's with an 8.8 in my last XJ, the diff never hung me up wheeling. When I was still on 33's I drug it all over Superlift in Arkansas. I hung on that 8.8 more times than I hung on anything else. I agree with Frank, for 33's keep the 8.25
