Here we have a complete rear differential assembly assembly removed from a 2021 Mustang GT with Track pack option. This will have the torsen and 3.55 gears and should fit years 18-21 Mustangs with the same features. Please confirm fitment with vin or part number BEFORE buying. Please view all of the photos you'll get the exact item shown. I'm also parting out the rest of the car, so If you need anything please send an email so I can list it on ebay for you.
