      Description

      Put the Power to the Pavement. Boost your Mustang's performance and improve road handling with the Yukon Rear 5-Lug Conversion Kit. This Yukon Kit includes an 8.8in 31 Spline Duragrip Posi Differential, a pair of 5 Lug Axles and all the bearings and shims required for installation. This Yukon kit is ideal for those Fox Body owners 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 and uses 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 1979-1993 Mustangs equipped with a 8.8" rear differential housing.

      Technical Note. V8 Mustangs came from the factory equipped with 28 spline axles. 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.
