And the re-gearing will run $400-$500 for parts and that same amount for
labor.

None of the other 'bolt-on" products will get you the necessary power out of
the 2.5 liter engine.

Your differentials should have a tag that shows the gear ratio, if not you
can get a "Build Sheet" from your corner DC dealership... all you need to
provide them is the Jeep VIN number.

Build Sheet:

Once you know your stock gear ratio there are charts to point out the
appropriate new ratio given your new tire size to regain 'stock'
performance.

Good point about the exhaust. Better gas mileage wouldn't hurt
either. Worth the try at least.
Regearing the axles does make the most sense. I just need to figure
out what I have and how to change them. I'm not looking for much
performance gain.

Thank you for your advise. I much appreciated it.

Re: 97 TJ 2.5L performance parts
 

Normally the 2.5L engine with a manual will be geared at 4.10's, but I guess
they may have 3.07's with the automatic (the auto 4.0L does). You would want
to get at least 4.10 gears. If you already have 4.10 gears, consider 4.56.

Your transmission doesn't have an overdrive, so after you regear get used to
your tach being at around 3000RPM at highway speeds and your gas mileage
going south.

You'll also need to replace your speedometer sender gear with one that will
compensate for the new gears. The shop doing the gears can do it.
