Description
Duragrip Posi Differential. Stop doing those ridiculous one wheel burn outs by upgrading to a Yukon 8.8in 28 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 equipped V8 Mustangs from 1986 to 2004, including GT, Bullitt, Mach 1, and SVT Cobra models. Requires use of 28 spline axles. (Will not fit 2003-2004 SVT Cobra).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 will this fit on a 98 mustang v6 that has 28 spline 8.8in axles?

  • In 1998 ford used a 7.5 rear in the v6 so unless it has been swapped to a GT unit it will not fit your car.

    Traction!

    Well my stang is 13 years old and the rear diff was not working properly I ended up doing a couple of ridiculous one wheel burnouts and that is never a good sign specially when it comes to LSD. So I search around the Internet trying to find a solution and then I found This LSD 28 spline by YUKON at AM I love the grip the car handles much better throw rough cornering, lunches much faster than before overall is great I have grip all day long and I enjoy the 11 looking burnouts.

    Grip!

    Needed gears done in my 99 Cobra and I bought this as an upgrade to the stock ford unit. I honestly didn't know what I was missing until this thing went in; talk about grip on all kinds of surfaces and horrible roads! If you are going to stick with the stock 28 spline axles then this unit is excellent bang for the buck at $350. I though I had grip before and I see how wrong I was, the Ford unit has nothing on this!
