Put the Power to the Pavement. The factory differential found in the SN95 Mustang doesn't exactly allow for maximum power and maximum torque to hit the roadway. With a Yukon DuraGrip Posi Rear Differential, you'll be able to maximize the performance of your Mustang, improving its traction without ruining its responsiveness. This Yukon Kit includes an 8.8in 31 Spline DuraGrip Posi Differential, a pair of 31 spline 5 Lug Axles and all the bearings and shims required for installation. This Yukon kit is ideal for those GT and SVT Cobra owners who are looking to upgrade their stock differential and axles for better traction and more impressive burnouts.

Posi Rear Differential. The DuraGrip Posi Rear Differential features a case constructed from a heavy duty nodular iron and boast forged 4320 steel internals and composite clutches for dependable heavy duty performance and long life.

31 Spline 5 Lug Axles. Stronger than OEM, Yukon Gear manufactures their 31 spline 5 lug axles from high quality 1541H alloy steel for superior strength. They use a rolled spline process that produces an axle spline that is up to 30% stronger than standard cut splines.

Durable Alloys. The parts in this Yukon Gear and Axle kit are built from high quality, heat-treated metal alloys for long-term durability. Top quality ensures extended use before needing to replace the parts. This complete axle kit includes everything you need for optimal road handling.

Application. This Yukon Gear 8.8 in. DuraGrip Posi Rear Differential Upgrade Kit with 31 Spline 5 Lug Axles is designed for 1994 to 1998 GT and SVT Cobra Mustangs equipped with a 8.8" rear differential housing.

Technical Note. 1986-2004 V8 Mustangs came factory equipped with 28 spline axles, except for 2003-2004 SVT Cobras which were 31 spline. 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.

Q & A

Ask a Question

If I convert my 1995 GT over to this Yukon differential, will it allow me to use the 31 spline SR performance driveshaft for 96-98 mustangs listed here: http://www.americanmuscle.com/aluminum-driveshaft-9604gt.html Or are there other issues I would run into? Also, the description says 5 lug axels, but the picture looks like 4 lug. Can I assume that the 5 lug description is correct? Thanks!
