Re: 97 TJ 2.5L performance parts
You have 4.10 gearing. 4.56 will return some performance and gas mileage.
Get the 4.56 gears, cat-back and 4.0 throttle body, and be happy.
FWIW, my 89 YJ 2.5L pushed my 33's around town and on the highway with no
problems, but it was a five speed. The 2.5L is a great engine.

I requested a build sheet from DaimlerChrysler. This should help.
In the meantime, I looked today at the rear differential cover. It
definately has Dana on it. Also, it is a small metal tag with stamped
numbers:
52111763
3 73 5957 <--I'm thinking this means 3.73 but am not sure. I
will take the cover off and see what's inside for sure. Don't know if
the previous owner(s) did any mods besides the tires and lift kit.
First, I guess, I'll need to go get some pumpkin juice for it.
I took the TJ out on the highway today. Got it upto 60MPH (on the
speedo), tacking approx 2700, I completed a mile in about 53 seconds.
I did this for (5) miles straight...each mile 53 seconds on a
stopwatch. Not real scientific.
I guess I was actually doing 68MPH. Good thing the speed limit on
that stretch is 70.

4.10 is your gear ratio.
