Limited Slip Differential.
If your stock rear end is not putting the power to the pavement you need to upgrade to an Auburn Pro Series 8.8in 31 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 ground giving you better traction and more impressive burnouts.Heavy Duty Construction.
The Auburn Pro Series Limit Slip Differential has a heavy duty design defined by its higher spring load and ductile iron carrier housing. The higher spring load and unique cone-clutch design will provide more torque and faster engagement for controlled power transfer and quicker reaction to changing load conditions. Making it the perfect Limit Slip Differential for a street or an all-out race Mustang.Recommended Upgrade.
Seeing that no gears are included with this Differential, you will need to reuse your factory 8.8” gear set. A better idea is to upgrade to a new set of steeper 8.8" gears to improve your Mustang’s performance.Professional Installation Recommended.
The installation of a Limited Slip Differential can be a very intricate process, so mechanical experience is highly recommended. AmericanMuscle recommends professional installation for the best results.1 Year Limited Warranty.
