rear end gear ratio

G.T. Rags · March 27th, 2007, 03:33 PM

what is the stock rear end gear ratio for a 96-98 gt. r they the same for convertibles or dif? I've found multiple sites claiming 2.73, some r 3.08, and I believe a 3.23 was tossed up in there.

Casper98GT · March 27th, 2007, 04:07 PM

yes. Look at the tag on youre rear end of give me youre vin and i can tell you

ChrisJ · March 27th, 2007, 05:16 PM

I would say you prolly have 3.27's in there...But check the diff tag to make sure...

ujslost · March 27th, 2007, 08:13 PM

mine has 3.27 stock

MustangMatt96GT · March 27th, 2007, 08:14 PM

Mine has 2.73!

slightly stoopid · March 27th, 2007, 10:10 PM

3.73 stock?

MustangMatt96GT · March 27th, 2007, 10:18 PM

no way! The lowest gear that the 96-98s had were 3.27 from the factory. There was also 2.73 but not 3.73s.

ujslost · March 27th, 2007, 10:43 PM

re read my post........it says 3.27!

G.T. Rags · March 28th, 2007, 07:52 PM

my vin # is 1FLAP45X0TF192629

MustangMatt96GT · March 28th, 2007, 08:27 PM

That wont help, on your drivers door jab there will be a sticker and then at the bottom of it towards the right you will see AX. If the letter is an A then you have a 2.73 or a 3.08. If you have a C then you have 3.27.
I was also wrong I said that 2.73s and 3.27s were the only axles, but 3.08s were also avalible.

G.T. Rags · March 28th, 2007, 10:26 PM

i put the vin number up there because casper said with it, he'd be able to tell.

MustangMatt96GT · March 28th, 2007, 10:27 PM

Well I dont think that you can determine the rear gear ratio by just the vin I think you need to look at the sticker on the door jab. Not to mention it would be easier!

True2theHorse · March 28th, 2007, 10:39 PM

Worse case you can simply jack the rear of the car up and mark the tire and the ground, then have someone rotate the tire one full rotation, and while you are under, mark and look at the drive shaft and count how many rotations it turns. IE..3.27 would be if the driveshaft turned about 3 and a quarter turns. It's really not complicated, but it is a sure bet worse case.

2007calispecial · March 30th, 2007, 12:00 PM

just do what mustang matt told you lol its so much easier, i think the 3.27's weremsort of uncommon though i am guessing you have 2.73

Mystry · April 2nd, 2007, 06:01 PM

Mine says E....

is that

but casper my vin is 1FALP42X4TF207816 if you could tell me too plz

1badpony · April 16th, 2007, 12:23 AM

My Axel code on the door of my 03 GT Convertible is LE, but on the rear end, I have a tag and one of the codes is 3L27, i'm assuming thats 3.27 limited slip?

Car feels like it has 2:73 to me, won't even break the rear tires and i've drive a good few mustangs, this seems to be the slowest for some reason.

mustang500hp · April 16th, 2007, 12:28 AM

by the way, i was wondering if 3.73 is the best gear ratio...i like them but i was just wondering your guys opinion.

MustangMatt96GT · April 16th, 2007, 12:42 AM

Get 4.10s!

Dxpsman · April 16th, 2007, 02:43 PM

Matt, you seem to be a huge proponent of the 4.10. Is there really a major advantage to the 4.10 over a 3.73?

Casper98GT · April 16th, 2007, 02:49 PM

96GTRagTop....sorry. Ford now has a 10 year limit to what i can see.

1badpony...3l27 means you have a locker rear end with 3.27 gears.

If youre running a n/a car go 4.10's or 4.30's. If youre F.I. stick to a 3.55 or 3.73.
