Well I purchased this thing not knowing what it had behind the front and rear diff covers. I pulled them off a minute ago, and the rear looks stock and the front looks like it may be upgraded, but may be some sort of stock locker... If I am correct they are 3.73s.
These are the numbers I pulled off of the ring gears and pinions.
Front
Pinion 11 Teeth - only had what looked like 2 + 3 etched in it.
Ring 41 Teeth - 10 13 01 Dana SE 37768 41-11 ST then 704 in big writing.
Rear
Pinion 11 Teeth - 44515 W L637 F and it had LO 776 etched in it.
Ring 41 Teeth - 11 02 01 Dana D 18515 P8L287 41 11 776
Transfer Case - New Process Gear
Mod # 231 J
5209 9211AB
12 1 01 C3 272
Some of the numbering looks like dates that would go with the year model of the vehicle which makes me think that they are stock. I am trying to upgrade them to get better Power/Top Speed.
