Trying to stay away from the OEM Trac loc dif. I would like to stay with a TQ bias difI just bought a diff off ebay Yesterday with 3:15 gears for $230 shipped..its being delivered Friday. I have 3:55’s now which render my 1st gear useless with a 6r80. Should be perfect for my set up...
Torsen makes some, but they are $$$, waveloc might buy they are also over 1k. I've thinking about a 3:31. Just can't find a taller tire I like to fit my set upYou wont find a irs torsen diff with 3:15 gears because ford never made them with 3:15 gears. You can build a torsen diff with a new 3:15 ring and pinion.
If you're stock and plan to stay NA. IMO the 3:55 is the better gear. For guys running boost 3:15 is easier to control on the street and keeps you out of 7th gear at the trackNot trying to high jack Your post but I’m new to the stang game is there a noticeable difference between the 3.15 gearing and the 3.55 gears? Paired with v8 & 10sp.
if your going with boost in the future You should keep them if not 3:55’s. I will sell you my 3:55’s once i get them swapped for my 3:15’s.I would gladly swap my 18 3.15 aluminum pumpkin for any other ratio.
