3.73 Torsen trade for a 3.31 Torsen

[Stang8]

My 2015 GT Manual has the Torsen 3.73 in the rear. I am looking to see if anyone with a Torsen 3.31 wants to trade before I swap the ring and pinion. My car has 15,000 miles and I’m located in Pennsylvania. Zip 18974.

You're gonna have to swap gears. The torsen never came with 3.31's on an S-550, only 3.55's or 3.73's

The 3.31 came with the Torsen in the Ecoboost.

I don't think the 3.31 in the ecoboost is the torsen.

The 2015-17 models only came with the torsen on performance pack cars with a 3.73 ratio. I'm not sure if the EB performance pack had the 3.73/torsen but the torsen was only paired with 3.73 gears from the factory. All other gear ratios came with the clutch style limited slip differential known as Traction-Loc.

Thanks guys. I was given bad info. I just ordered the gears from Ford.

EB/PP has 3.55 with Torsen. Otherwise 3.31 with clutch-pack.

Gotcha. There’s definitely some misinformation out there. I will leave this up just so others don’t make the mistake. I order The gears and I am rebuilding mine this weekend.
