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 2013 as well as 2011 to 2013 V6 Mustangs. Requires 31 spline axles. (Will not fit 2013 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.
