how do I find out?
seller dont know what rear he has...
- Thread starter boneblower
- Start date
I believe the rear diff cover, if still stock, should have it listed.
There is usually a tag on the diff. Lay down under the rear bumper and snap a pic.
:lol:
Use the VIN and pull the Ford Build Sheet.

He may be to busy blowingbone's :dw:
2011 gt 6sp mt......................but I'm in that section,thot it was a given....
anyway used that site to view the window sticker and that don't indicate what rear its got.
I have the vin is there another way to see what the cars got?
also kinda weird is that it says it has California emmissions even tho its an east coast car. Is that right for an east coast car?

If it doesnt list the 3.55/3.73 option on the window sticker it has 3.31 from the factory. Thats not to say that they were not changed out by someone else after it left the factory, and the rear end tag should say 3.31
If the window sticker doesn't list a gear option then the car has stock 3.31's
Delete all typed, no need for a three-peat

The build tag on the drivers door jamb will have the axle code. Get the code and Google search it.
But as someone else has stated, the gears could have been changed though.

It should be on your rear end cover somewhere...mine was right near the stop so unless you were fully under the car it wasn't easy to see.
I am not near my car at the moment but could have sworn the code is in door jam as well.
Once you find the code here is a list of common axle codes:
2011 2012 2013 Ford Mustang GT Axle Codes - 2011 2012 2013 2014 Ford Mustang GT

Like others have said, look it up by vin.
If you want to know if they've been changed then get the rear up and spin the driveshaft until the tire rotates one full time. However many times you spun the driveshaft is what gears you have (ie 3.31, 3.73, 4.10, etc)

If you cant find it on the cover or determine it by the vin. You can pull the cover and count the teeth on the ring gear and pinion gear. divide the ring gear number by the pinion gear number. That will give you the ratio.
People are making this much harder than it needs to be.
Get under the car and look at the differential cover. Done, simple and no need to type in the Vin.

The Vin # and door tag will only tell you what should be there. That includes the tag on the rear differential cover. If the guy says they haven't been changed and they all match then most likely they are what's listed. However the only way to be 100% sure is to pull the diff cover and divide the number of teeth on the ring gear by the number on the pinion gear. It's more work but your question will be answered.
This!!
mine says 3.73 but it has 3.55... the only real way to know and know for 100% certainty... pull diff cover and start counting ring and pinion gear teeth... divid ring gear count by pinion gear count...
