      Description

      Duragrip Posi Differential. Stop doing those ridiculous one wheel burn outs by upgrading to a Yukon 8.8in 31 Spline Duragrip Posi 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.

      Heavy Duty. Featuring a case constructed from nodular iron, this Yukon Gear Duragrip Limited Slip Differential boast forged 4320 steel internals and composite clutches for dependable heavy duty performance and long life.

      Application.
      This 8.8" Yukon Gear Duragrip Posi Differential will fit solid axle suspensions equipped V8 Mustangs from 1986 to 2014 as well as 2011 to 2014 V6 Mustangs. Requires use of 31 spline axles. (Will not fit the 1999-2004 Cobra and 2013-2014 GT500).

      Application Note. 1986-2004 V8 Mustangs came factory equipped with 28 spline axles. 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.
