Gear ratio\'s 31x10.50

I'm a returning jeep (grand) cherokee owner (I've been in withdrawls for 5 years), my last was a '91 limited 3inch lift 31x10.5x15 on 15x8 wagon wheels. I lowered the gear ratio's, but can no longer remember to what. My new rig is a '98 grand with a 4.0 liter. I'm installing the RE 3.5 sure ride lift + 265/70R16 BFG's (about 31x10.5) and I'm going to try the new rubber on the stock rims for now. I'm looking for some advice for a new set of gear's for the axle's. I'd like the ratio's as they sit with the original tires, and would like to stay in the same ball park after the lift/tires.

I loved my last ride so much my freinds were getting tired of me talking about, so I had to get another (project time).

Thanks for any help

I got the 4.0 in my 90 running 30x9 1/2 so trust me when I say go with 4.11. BTW, have you checked out that ORV park thats right along the interstate on the eastbound side? I live up in Fargo and go to the cities occasionaly thats how I know it's there. Just curious what it's like and if you take your rigs off road?

I don't remember exactly where but I am thinking it is right around your area or maybe more by Rogers, I always see it going there after the exit you need to take to get to it.
