Chyr 8.25 question

So I picked up a front and rear diffs. Paid $100 for the pair. Rear is a 8.25. Then a week later got a screamn deal on a parts XJ it also had a 8.25 rear diff. Finally got around to pulling the covers to check gear ratios and condition. Both are limited slip. So are all chyr 8.25s limited slip?? or did I just get lucky. both 3.55 ratios. Going to replace my 3.07s Its real gutless with the 30in tires.

You got lucky, not all 8.25s had limited slips.

Make sure and check the spline count.
