Limited Slip Differential. Is your stock rear end leaving you in the lurch? Then you need to upgrade to a Ford Racing 8.8" 31 Spline Traction-LOK Limited Slip Differential with Carbon Discs from AmericanMuscle. A Limited Slip Differential (LSD) sometimes referred to as a "Posi" will allow both rear wheels to put the power down on the pavement giving you better traction and more impressive burnouts.
Carbon Discs. This Ford Racing Limited Slip Differential uses the same carbon fiber clutch pack used in the Cobra and Shelby SVT Mustangs. Carbon-fiber friction plates are much more durable and are designed for higher torque over there stock counterparts.
Application. This Limited Slip Differential is the same original equipment used in the 2003-2004 SVT Cobra Mustang. It will fit both solid axle and independent rear suspensions (IRS) equipped V8 Mustangs from 1986 to 2012 and 2011 to 2012 V6 Mustangs. Requires 31 spline axles.
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.
