Limited Slip Differential. Make it easier to warm up your tires and do more impressive burn-outs with a Ford Racing limited slip differential (LSD). This "Posi" differential will help you put your Pony's power to the pavement and improve traction and handling in all conditions.

Ford Racing Quality. When adding parts to your Pony, trust the folks that know it best to provide top quality components that are made to perform and last.

Heavy Duty Clutch Style. The Ford Racing 8.8" Trac-Lok limited slip differential uses heavy duty plate-style clutches for superior durability and performance.

Application. This 8.8" limited slip differential will fit both solid and independent rear suspensions in 1986 to 2004 V8 Mustangs equipped with 28 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.

Technical Notes. You will need to reuse your factory 8.8" gear set, or upgrade to a set of our 8.8" rear gears for this differential. No aftermarket gears are included. For normal driving conditions we recommend you use 75W90 gear oil (the same weight as factory). For colder temps or race use we recommend 75W140 weight gear oil. Note that Royal Purple oils already contain friction modifier, which is required with your initial gear oil fill.

Fitment: 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

    Overhaul

    When I did the ring and pinion (upgrade to 3.73) I replaced the Differential as well and all the bearings. Car had 130k and needed it. This was a no brainier and simple install.

    Verry happy with the Differential

    I am very happy with the Differential I put it in my car along with a set of 4.10 gears and the differentaial holds up great! I was very pleased to see the new Differential Hold up to the horse power I was putting out and I would recommend everyone to do a new rear differential if they plan to do gears and this kit comes with everything needed.
