What is the stock axle ratio on the 1998 GT? I checked my repairs manual and my code, and it had two different letters....very cfonfusing. So can anyone tell me please ?

i believe the standard is 2.73 with optional 3.27

thanks, so it appears my 3.73 gears upgrade was a pretty decent jump!

My '98 GT vert has 3.08 gears. I believe '99 to '04 had 3.27 gears and the new '05 & '06's have 3.55. In the earlier year Mustangs, they shipped with a variety of rearends so check your code on the door jam. Door jam only, forget the owner's manual. During different production runs Ford has a tendency to change gears, so to speak. Many varieties out there in the earlier models. I also believe all the 5.0's were shipped with lower ratio gears than the 4.6's as standard equiment. Here is a calculator to help you out: http://www.tchracing.com/tech/gearcalc.php

Yea i compared the doorjam one with the repair manual I got (the big one for mechanics), except that instead of having one letter code it has two WTF lol so i gave up I think M is 2.73 and E is 3.27 (im too lazy to look again) but in my doorjam it said ME (as an example) wow...

I think Deannostang is right, 3.08

jack up the rear tires spin the tire one revolution and count how many times the drive shaft spins in comparison.

I am trying to find the ratio of my axle also. The door sticker says ME. what ratio does that state for a 98 GT?
Thanks.
