Re: How to recognise Ford 9 inch Diff

If you are not going to put slicks on it and do high RPM launches don't worry too much. In a street application with an auto tranny you should have no problems.

The two look almost exactly alike with the exception of size of course. Here is a really good page with ID info and much much more....

Mate, just have a look under the car from the rear. If its a borg warner diff you'll see a plate bolted to the back of the diff roughly the same size of the centre. A 9" won't have that.

Just read some of the info in the attachment from what I saw last night looks like it may be an 8 inch (DOOOO) will check 2night. Very informative piece though will archive that for when I am looking for a nine inch if thats what i end up doing.

Cheers OhioXB

Re: How to recognise Ford 9 inch Diff

I've accumulated a bit of links in my research on Fords. I was a Mopar man all my life until 2003 so now I am getting up to speed on Fords. I had a basic knowledge of them but little in depth knowledge. The internet is a wonderful thing!

A buddy of mine drag raced a 67 Mustang with an 8" rear end and manual trans. He said he made 7,000 RPM launches for 4 race seasons before he blew up the rear end. After hearing that I had no problem having him build the 8" for my wife's '66 Mustang with a street engine and automatic tranny. It's got an Auburn Posi unit in it with 3.25:1 gears and 26" tires.

Re: How to recognise Ford 9 inch Diff

8.8" are tough. Every mustang late model runs a 8.8". Dont worry about the strength, Its prob been fitted to you XL is it?, because it would have a narrower wheelbase than a XY or XA width falcon 9" diff. and those XK-XP rear wheel arches def wont acommodate anything more than stock width.. A mate has a XM sedan 302 5speed and runs a borg warner centura diff for last 3 yrs no probs..
i run apprx 365RWHP in my mustang with 8.8" no probs
