28 or 31 splines?

[wolfstang03]

Im looking for posi. for my 2003 gt. I'm thinking stock is 28 spline. can somebody confirm please. A.m. has a ford locking diff. for like 200... I didn't think that was a bad.deal.

as far as i know all gt's had limited slip differentials. you can upgrade to the carbon fiber clutches that i put in my car or ive put oem ones in for people with the thickest shims to make them grab harder. sure they'll wear out a little quicker but if its not something you drive everyday youll be perfectly fine. it all depends on your power level and how hard you drive.

Iike said above your gt would already have limited slip diff. (posi) .... If you do get a one wheel peel you can do the rebuild kit and upgrade to the carbon clutches ... But it is 28 spline stock

I have an eaton 8.8 unit 28 spline that i crack the carrier in...the clutches are brand new considering i only drove it for like 3 months before the carrier cracked... i ended up buying another eaton( weird it's a new design and comes with a year warranty) think they had issues with the carriers one i had?

but anyway if you just wanted to upgrade the clutches i'd sell you mine. dont know what they're worth?

Is that the problem (clutches) a while back my buddy said I was getting a "one wheel peel" and I thought he was nuts.. then over the summer I noticed the one mark from doing a burn out and just thought the gt lacked the locking diff.

yea look into it....the guy that does my performance work told me not to throw it out bc the clutches were still brand new and some people look for that kind of stuff.... hope it will work for you. get it out of my work room and help you out cheap!
