Description
Limited Slip Differential. If your stock rear end is not putting the power to the pavement you need to upgrade to a 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. The Auburn Pro Series Limit Slip Differential has a heavy duty design defined by its higher spring load, to 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.

Application. This Auburn Pro Series Limit Slip Differential will fit both solid axle and independent rear suspensions (IRS) equipped V8 Mustangs from 1986 to 2014 as well as 2011 to 2014 V6 Mustangs. Requires 31 spline axles. (Will not fit the 2013-2014 GT500).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.

Technical Note. You will need to reuse your factory 8.8” gear set, or upgrade to a set of our 8.8" rear gears required 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.

Fitment: 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 Details
