Just curious :ninja: :D will a 3.73 Gear for a 8.8 rear end work with a 03 cobra IRS? I have some people telling me there the exact same, but others saying that it wont? Just curious since i know there are a good number of other cobras that go through this area!!!!!! :goodjob:

You must spread some Reputation around before giving it to TransAxle again.

LOL see thats the same problem i am in, i go to alot of well infoed mustang sites and everyone just list the ring and pinions by what they are, and not for cars. Like 87-93, 94-98, and 99-04 i cant find anything that says GT, Mach 1 and then Cobra's! :???: :thinking:

I'm having a similar problem with my nova. Trying to get a set of 3:73's but have found six different answers on what the spline pattern may be. Your best bet might be talking to a Ford Techncian, our someone else who has put them in. In anycase good luck finding the answer.

Let me talk to my buddy at Liberty Ford that posts on Modular Depot. It may take a few hours to get a response though.

Yes, the gears for an 8.8 rear end will work for a cobra with IRS. THis is straight from a Ford parts expert.

its an 8.8 center section, and thats where the similarity ends. all 8.8 gears will intechange into each other. thats why if your looking for a cheap 31 spline carrier got to pull a part and find an explorer:goodjob:
