    Torsen T-2 Differential. Does your factory rear end just leave you spinning your wheels? Then upgrade to a Ford Racing T-2 "Torsen" Differential from AmericanMuscle. A Limited Slip Torsen Traction Differential uses a worm gear friction system that ensure your engine's power is transferred to the wheels with maximum traction for improved handling.

    Application. This Ford Racing T-2 Torsen 8.8" Differential will fit both solid axle and independent rear suspensions (IRS) equipped V8 Mustangs from 1986 to 2014 and 2011 to 2014 V6 Mustangs. Requires 31 spline axles. Application Note: 1986-2004 V8 Mustangs came factory equipped with 28 spline axles, except for 2003-2004 SVT Cobras which were 31 spline. All 2005 and newer V8 Mustangs come equipped with 31 spline axles.

    Specifications:
    • 8.8" Limited Slip Differential
    • Will accept anti-lock exciter ring
    • Requires 31 spline axles
    • Requires 3 quarts Gear Oil
    • Requires 4 ounces of CM-19546-A1 friction modifier with initial fill
    • Fits solid or independent rear suspension

    Technical Note. You will need to reuse your factory 8.8” gear set, or upgrade to a new set of our 8.8" rear gears for this Limited Slip Differential. No aftermarket gears are included. For normal driving conditions we recommend you use 75W 90 rear gear oil. This will give you the same oil weight as factory. For colder temps or race use try 75w 140.

        Is this usable on a stock 2013 mustang gt? Also what is the difference between this one and the $230 ford racing one w/ Carbon DISCS? Do I need Carbon DISCS?

        • The Ford Performance T-2 Torsen Differential can be installed on a stock Mustang but will require some other upgrades as well. This differential is meant to be stronger and handle a lot more power than the factory differential can, which means putting more power to the ground. This differential also requires 31 spline axles,1986-2004 V8 Mustangs came factory equipped with 28 spline axles, except for 2003-2004 SVT Cobras which were 31 spline. All 2005 and newer V8 Mustangs come equipped with 31 spline axles. You will need to reuse your factory 8.8” gear set, or upgrade to a new set of our 8.8" rear gears(http://www.americanmuscle.com/rearend.html) for this Limited Slip Differential. No aftermarket gears are included. For normal driving conditions we recommend you use 75W 90 rear gear oil. This will give you the same oil weight as factory. For colder temps or race use try 75w 140. As far as differences between the two this is an all around stronger differential meant more for racing, the Ford Performance Traction - LOK Limited Slip Differential w/ Carbon Discs is more for the enthusiast looking to put more power to the ground and have a more responsive limited slip than the factory setup.

        Why are you recommending a friction modifier additive when the Torsen diff doesn't use any type of friction material?!?

        Will this work well at the drag strip

        • The Ford Performance T-2 Torsen Differential can be used on both street and strip.

        will this work with all of the stock bearings in a 2014 mustang v6

        • We highly suggest to get a new set of bearings with the installation of any new differential for your Mustang to ensure proper fitment and, most importantly, functionality.

            New Differential

            Want to take it easy on the new ring and pinion, so cannot really feel the new Diff yet, but when I get that chance look out.

            Smooth as butter

            Paired it with ford Racing rear gear, 3.73. They work just fine and smooth. Still in the break in period, though.

            Launches are much more fun now. Traction is much improved over old broken Limited Slip.

            Omg

            This differential changed my car along with the 3.73 gears. It's like driving a new animal. Took the vibration out of my rear end it's just butter smooth. Money well spent.

            GT Performance Package

            I enjoy the performance of this rear end. I have it on a 1989 fox with a 345 HP gt40x crate engine. Under heavy acceleration the rear end really hunts for traction and in a curve if you break traction it's self corrects nicely and wants to straighten the car. It's also cool to have a t2 with 3.73s in your 89 5.0, it's just like a 2017 with the gt performance package.

            After almost a year of factory diff problems I decided to replace the gears and diff. what a difference this set up has made for the performance this car can put out.

            Best modification to date

            I installed the Torsen T2 in my 2011 GT350. I track the car 4 to 5 times a year and was looking for improved track performance. To my surprise, the street performance was also vastly improved. The car in now smoother and quieter. My car has 610 rwhp, and smooth application of power was an issue with the stock differential. The Torsen has greatly improved traction, even at WOT. I could not be happier.
