What gearing should I get?

My Jeep is getting pretty heavy with all the aftermarket parts that I am adding and losing some noticeable power. I would like to know what kind of gears I should get to gain better overall performance for automatic tranny. I have 31x10.5x15 AT and might go to 33's with OME 2.5" HD lift in the future. I'm using this as a hunting rig and DD.

Below is my jeep specs.

2000TJ
Stock Suspension
Stock engine
I6, Auto
3.07 gear
31x10.5x15
Kargo Master cage, safari rack
Front and rear Body armor bumper with tire carrier
Body armor slider
Front winch

Thanks-

4.10s would be good for 33s with your I6/32RH combo.

So 4.10s would work with 31" tires for now?

I would just look for a complete set of axles out of a 4 cylinder jeep and just swap em that way. Otherwise I have had good luck with Yukon gears

After talking to a local Jeep specialist, he advise me to gear both axles to 4.10s on a 31x10.5x15 tires. This will increase my rpm to around 2200-2300 at 65mph. Does this sound right? I want a low end torque and be able to maintain speed or increase when going up hill on the freeway. I might just stick with my 31s tires since going to bigger lift and tires will open up another credit card.
