Cool, is that with the same carrier or did somebody finally decide to make another one?

It's just a ring and pinion to my knowledge.

Once I dig around with my "gear guys", i'll keep you all posted on whats happening...

Honestly, NO CLUE...
All I can say is that 8.25 is larger then D35... and seems to have reputation to hold up better a little...
My buddy on the red XJ has D35, and we both run identical tire size/lifts, and dont see much difference at this point...

I may be wrong but I think the measurement is the center of the gear mesh face. Also, there is more to the strength of a differential than the ring gear size.

I think once your buddy gets to a point where he needs to put the pedal to the metal and he puts a lot of torque on the 35 he'll see a difference pretty quick.

Well, seems like business side of things is going a bit better then I expected, so I will be able to get my gears/lockers done sooner then I hoped...
:wings:So, now i figured that may be just go selectable both front/rear...
Only problem - ARB seems to be the only choice... I didnt see a selectable Detroit from Chry8.25...

Detroit isnt a selectable, correct...???
ARB is the only option for a selectable into a Chry8.25, from what I understand...
I was hoping I could get the E-Locker put in to the front and back...

No. A Detroit (or Aussie, LockRite, and a few others) are ratcheting automatic lockers. They require no input from you to lock and unlock. The axle shafts can (under various conditions, such as coasting through a turn) rotate at different speeds.
A spool does not ratchet. It physically fuses the right and left axle shaft together so that they cannot go at different speeds; you can duplicate this by effect welding your spider gears to your carrier. The ARB,when you elect to engage it, creates a spool condition - a solid locking of the two axle shafts.
As for the original question:
With 25% overdrive and 33" tires and a trailer >1500 lbs, I'd err on the side of 4.88 gears. In snow/ice, I'd NOT put an automatic locker in the front under any circumstances and would be very hesitant to do so in the rear. If you don't deal with snow/ice on the highway, well, I've never lived in such a place, so I don't know what's best.

Additionally, if you are dealing with snow and ice covered roads I'd be inclined to only install a manual locker that was a true open differential when unlocked (i.e. not a LSD when not engaged).
IIRC only the ARB and OX are open differentials when not engaged. But I could be wrong on that. I'm only interested in ARBs so haven't bothered to stay current with the newer offerings.
