will be using a ford 8.8 rear and need to know the stock gear to match it on the AWD setup

3.545

IIRC it varies between the auto and the manual. Will edit post once I look up which is which.

Auto is 3.307. The odds that he is going auto are pretty slim, but in case he is that is the gear ratio he would need.

ratios available for 8.8 are 3.08/3.27/3.31/3.55/3.73/3.90/4.10/4.30/4.56/4.88/5.14/5.71/6.14

im using the same setup in my mirage and the close one is. the factory ford 8.8 w/ the 3.55 gears you shoudnt have no problem.thats the closest one to the factory 3.545 1g or 2g if you round this number up it gives u 3.55.count the pinion gear it should have 11teeth and the ring gear should have 39 .divide 39/11 that is 3.55 and walllaaaaaa

what car did u pull the 8.8 from? (if u got it allread).. and what width is it?

My 8.8 came out od a Thunderbird turbo coupe. The guys at Moser told me that all 8.8's are the same width and the only thing that changes is the lenght of the axle shafts.


On the t-bird Axles there as a ABS tone ring and a disc brake set-up so the axles stick out of the housing a bit further then some other models. I Told the guys at Moser I wanted them 3/4 of a inch shorter then the T-bird ones. Turns out that is the standard width Fox body mustang axle. So I had 5.0 mustang axles drilled with the 4x4.5" Colt wheel bolt pattern.

The gear count in the 3.55 gears is the same as a DSM rear diff, Mitsu spent the extra cash to print 3.545 and Ford saved .000001$ per car by printing 3.55 LOL.
