Rear gear question

TruStangr92 · May 29th, 2011, 03:52 PM

Could someone please tell me what the stock rear gear was for the '92 GT? I believe it was either 3.08's or 3.27's but cannot remember which.

Thx, Dave

Auto or stick? different for each. my 91 auto had a 2.73 originally

Oh, my bad man. 5 speed manual.

Pulled this from another site....
With the transmission in neutral and the car safely raised up, one turn of the rear wheels will spin the driveshaft a number of times.

2-3/4 turns would be 2.73's

3 turns would be 3.08's

3 1/4 turns would be 3.27's

3 1/2 turns would be 3.55's

3 3/4 turns would be 3.73's

Thanks for the info but I am not sure how many turns it made when I had the stock gears in. I have had 3.73's in for the past few years. I thought I would be able to Google the answer but not as cut and dry as I had thought.

take a sharpy draw a streight line down the driveshaft about 6 inches and count how many turns that goes around compared to the tires 1 time of going around.

If you have 3.73 in it now why do you need to know what stock was ?

3.08 and 2.73

autos had an option of 3.27

I purchased a PMS from AFM and with the computer came a sheet that I fax back to them filled out with various info so that they can setup a tune for me. One of the questions is "original ring & pinion and current ring & pinion".

Thanks for the info ryanw

My 91 GT with a T5 came with 308's but I changed it to 410's. It's not too much gear as I've heard some claim.

Stock gear ratio would be 2.73 manual or auto, optional for a 5 speed would be 3.08, optional for the auto would be 3.27.
