Do all 06 Mustang GT's with a 5-speed manual come with 3:55 rear end gears? I don't know what I have in my stang, I just got it. How can I find out?

I know all 05's had 3.55's with the manuals, so im assuming the 06's did too. I think it changed in 07... But just to be sure, take a peek under the car and look at the rear end. It will have it listed right on it... You might even be able to read it W\O putting it on a lift....

I checked and found out I got 3.55's...

3.55 unless they were changed by previous owner.
4.10 or 4.30 are the gears of choice for the M5's.
Worth around 3/10 give or take in the 1/4 mi.
