This depends on your cruising speed, driving habits and existing axle ratio.
If you find now that fifth is a bit too much and fourth is not enough, then
you may find that fourth is just right, and fifth is useless after the
change. There are like three common axle ratios, I think, so it would be
hard to answer in general. If you use it off road then the existence of low
range may keep things sane. After you change the tires try it out on that
hair-raising descent where you always needed first gear low. ;^)

I can speak from experience on your setup, but it depends on your stock
gearing. When I got my TJ (4.0L 5-speed) it had the 33's and the original
gearing of 3.73. 5th gear was pretty much worthless for any incline. Spent
allot of time in 4th gear on the highways. It wasn't long till I changed to
the 4.56 gears and got the proper speedo gear. A few months ago my son
bought a YJ (4.0L 5-speed) with 33's and stock gears of 3.07. Not only was
his 5th gear useless but his 4th was sorry also. On any incline he has to
go all the way to 3rd to maintain speed. We are in the process of switching
out his axles from a donor 4 cylinder YJ (4.11 gears).

Ok... well... if I am hearing everyone correctly... 33"s with my setup
would be bad, unless I get new gears? How much can I expect to pay to
upgrade my jeep to new gears. Should I even go this route or just wait
until I have a 4.0L jeep later on in life.

Keep in mind in addition to the gear change, you will also need to lift it a
bit to clear the 33's, and you only gain 1" of clearance under the axles
with the 33's vs. the 31's.

So figure $300+ per axle for the gear change, 500+ for a minimum 3 inch
suspention lift (3 inch body lifts are way more trouble than they are worth,
and look stupid to boot), plus the new wheels and tires (new wheels because
12.5" wide tires on the stock wheels will contact the upper spring perches).

Or slap a set of 31's on and be done with it, use the money you saved from
not lifting to get a winch, so when you do get stuck you can still get out.

Which should you do? Hey man, it's your money! :-)
