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.

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. TJ |
