28 or 31 axle

[ashleyroachclip]

All Mustang factory 8.8's are 28 spline .
You will never find an 8.8 from the factory , with 3:73 gears .
All fox 8.8's had 28 spline axles .
I own a Mustang , and also spray it , have had the 8.8 w/28 spline axles in for years , and have never had an axle failure .
Did a 5 lug to my Mustang , with 2 left side ranger axles .

The axles aren't the weak point in that set up, it's the carrier. If you are only after 5 lugs and you indeed have a stang rear here is what you do. Go to the junkyard and take 2 left side axle shafts. The 7.5 and the 8.8 use the same shafts. A mustang uses the same shaft on both sides and they happen to be the legnth of the Ranger left side shaft. If you are upgrading everything then right on; you have the right idea.

sorry, not true. not only do they come that way quite often in f-150's, explorers, and rangers...but ive seen a few (newer) mustangs with them.

ironman, the housings are different between the 31 and 28 spline axles....you cant convert your current axle to 31 spline by just slapping in a carrier and/or axle shafts. your stuck with the 28 unless you go find a complete 31 spline axle.
