XJ gear vs. Tire

[Sleeps In Jeeps]

I really hate to thread jack like this, but here is what my jeep has, copied right from the ad the PO posted. Looks like I may already have the HP D30?

122,3xx miles on 4.0HO with AW4 automatic transmission
* NP-231 transfercase with Advance Adapters SYE modification'
* Non vacuum disconnect HP30 front from 89 XJ
* Power Steering, manual windows and doors, A/C (r134a... worked last summer... still have a recharge can if it needs it)
* 3.5" Rubicon Express SuperRide lift kit
* replaced front to rear brake hard-line
* RE braided SS extended brake line in the rear
* RE brake line extensions in the front
* Brand new RE mono-tube shocks all the way around (about 2k miles on them)

It's certainly easy to check..... just look under the the rig at the front axle pinion and see where it comes out of the housing.

What am I looking for? This is my first Jeep, can you tell? lol

Low Pinion on the left, High Pinion on the right:

Or the even simpler way would be to read that ad It state's it's a HP (high pinion) Dana 30. Pretty damn sure that only 00-01 XJ's had the LP.

As for gears, 3.55 with the auto. Also, I don't think that losing the ABS is a con.......kind of a PIA in my opinion on a rig that's off road. Unless you have a easy way to disable it.
