Description
Limited Slip Differential. Stop doing those ridiculous one wheel burn outs and upgrade to a Auburn High Performance Series 7.5in 28 Spline Limited Slip Differential from AmericanMuscle. A Limited Slip Differential (LSD) sometimes referred to as a "Posi" will allow both rear wheels to plant the power to the pavement giving you better traction and more impressive burnouts. Application. This Auburn High Performance Series Limit Slip Differential will fit solid axle equipped V8 Mustangs from 1979 to 1985 as well as 1986 to 2010 V6 Mustangs. Requires 28 spline axles. Application Note: 1979-1985 V8 and 1986-2010 V6 Mustangs came factory equipped with 28 spline axles.

Technical Note: You will need to reuse your factory 7.5” gear set, or upgrade to a set of our 7.5" 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.

  • This LSD differntial does not include a gear set. You can reuse your factory gear set or you can upgrade if you'd like while the housing is open! You can use your stock drive shaft and nothing else is needed for installation aside from new rear gear oil!

  • Yes, all 86-10 V6 Mustangs came equipped with 28 spline axles from the factory. This would be a great addition to your Mustang, putting the power where it needs to be - the pavement! You won't be disappointed with this investment!

    THIS IS AWESOME!

    June 10, 2012

    First off this is a must have. I cant get that stupid smile off of my face still. It puts down power more evenly and helps when your taking off as well, oh and the sweet two wheel burnouts! Its a great mod and a must have for ALL V6 owners! However it is a bit pricey, compared to the old ford one, which is not being made anymore. It is expensive but totally worth it! While your down there get a rebuild kit with everything you need in it! Overall, I am SUPER happy i got this! Thanks AM! Hope I helped everyone!

    completely changes the car's handling and makes it move through a turn. It's definitely an expensive unit but since it's good for more power than any sixer anywhere can make n/a, it will last a good long time and is worth it. This, paired with a nice set of gears will wake up anyone's six.

    V6 Stang LSD

    December 15, 2012

    Absolutely love this product with the auburn LSD and the 4.10 Ford Racing gears makes a huge difference in the drivability of my car it squeezes every last horse out of your v6. You can feel the biggest diferance is right off the line, and between 3 grand and 5500 rpms. The description says it ands 5 hp but it feels close to 100. I would definitely recommend these two together to anyone with a v6 that's looking to put a little pep in its step. O best of all no more one wheel peels!!

    This product is a must for street or drag for Mustangs!

    January 19, 2013

    We removed the stock gears and installed the 3.73 gears with Auburn Posi-Torque in four hours on an 02 Mustang. We renewed the rear brake pads at the same time. We also had to re burn the computer chip to obtain the correct speedometer reading. The total performance was noticed immediately with improved shifting through the automatic transmission. We highly recommend this product. Al Chornyi

    March 23, 2013

    Having prior knowledge of a rear end, puttin this in with the 3.73 gears, my car definitely picks up much better! And with the two tire marks instead of one, this little sixer is definitely more fun to drive around! It is a must!
