Need help finding the right axle ratio!

I am hoping that some of you guys can help me with this dilemma:

My 05 4cyl TJ has 31" tires and the stock 3.73 gear. Needless to say that this is not the quickest rig out there! I was too damn cheap to buy the 6cyl in the first place and now I'm paying for it with a variety of performance mods.

Here are my questions:

1) What's the benefit of installing a 4.10 gear?
2) Does this require additional mods of any kind -- e.g. axle?
3) What's the approximate cost of re-gearing?

I appreciate your help and comments!!!

I thought all 4cyls came with 4.10's?

If you do have 3.73's it would be a waste of money to swap to 4.10's, IMHO.

Auto 4cyl had 3.73. It will cost anywhere from 800-1500, really depends on the place. Switching to 4.10's would be a waste, with a 4 I'd go 4.56 or 4.88.

if you plan on going bigger like 33s or 35s in future, regear to 488s
