I think I'm going to start buying parts to get my TJ regeared from the
dreaded 3.07 that I have now. I THINK that 4.10 makes sense for me; I'm
not planning on going with huge tires or lifts. Most likely 31's or maybe
32's. I know with 31's I'd be a little low-geared but that's OK; i don't
need to go faster than 75 mph in this vehicle.

Vehicle is a 4.0L TJ, 5-speed tranny.

So... would you all agree that 4.10 is the way to go?

The 4.10's would be a good choice, especially with the 32's.

yep, but if you are even thinking about bigger tires some day, get 4.56.
Tons of people run 4.10s with 31's and love it. You will be happy. I have
4.56s and 31's and like it but am planning on going to 33 in the near
future.

You mention going 75 mph. This tells me that you need to drive your jeep on
the highway at least as often as it will be off road. You probably fall into
the 80/20 or 75/25 highway/offroad use pattern of the majority of jeep owners.
If so, you will hate 4.56 gears unless you run 33" or 35" tires. You will
probably also hate 4.10 gears with 31" tires.

4.10 will be a good choice with 33" tires. IMO, if you are going to spend the
money on gears, go with 33" tires rather than 31". (32 is an "odd" size with
less choice in brand/tread than either 31" or 33".) My logic in going from
stock directly to 33" tires is to avoid the considerable expense in
underestimating your ultimate needs, which will result in changing gear
ratios/suspension mods twice.
