3.27s come stock. I have 4.30s but their not for everybody. i drive a mile to school everyday but a lot of people do a lot of commuting. i still get 24MPG with the 4.30s on the highway. 3.27s with cruise control i got about 27-28MPG. Get a nice midpipe and catback to let the engine breath better + youll love the sound.
Im pretty sure mine has 2.73s.

New Edges came with 3.27's. Some 94-98 came with 2.73's.

My axle code is M, which I believe is a 2.73, tried to do a quick search and found that for 87-93 M was 2.73 and E was 3.23. Ill try and confirm if thats true for 94+.
