We use 2006 to 2010 Ford Explorer IRS 8.8 rear differentials in our kits. You can source it yourself to save on the core charge or we can supply it for $250. 



The Ford 8.8 design was first manufactured by Ford Motor Company in 1983. The axle was developed to replace the Ford 9-inch axle. The 8.8 IRS first saw use in the 1989 model year Ford Thunderbird and later Ford adapted the independent suspension differential into to its 3rd generation Explorer and 2nd generation Expedition SUVs. The Mustang first used the 8.8 IRS on 1999-2004 Cobra models.


Why do we use the Ford 8.8?

The Ford 8.8 differential is famous for being ahead of its time, its light weight (less than the iron BMW M differentials), it's strength and its aftermarket parts selection. Its the most popular differentials to swap into a variety of cars for good reason! A huge variety of gears, limited slip carriers and rebuild kits are available from all the popular sources like Summit Racing, JEGS and your local auto parts store. This 06-10 Explorer style differential uses an aluminum housing with two forward mounting points and a rear cover with built in mounting points which makes it perfect for swaps.


Gear Ratio Choices:

A variety of gear ratios are available, but you get to save some money if you select the 3.55:1 ratio, as that is standard and comes in the core unit. With those, we will install the new carbon plate LSD, new bearings and axle seals. On units that receive a new ratio, we install new Motive brand gears  along with a complete rebuild kit including a solid pinion spacer.


LSD Options:

Our favorite LSD is the Carbon Clutch type! It is quiet, locks super well, doesn't chatter and feels great on the road & track. We have proven its capabilities on the track all across the country in our Ford 8.8 swapped Time-Attack E46 which always is in contention for wins. We supply this differential in all of our kits, but if you would like something different please reach out to us via email. 



All parts SHIP FREE, which saves a ton because shipping differentials is like shipping lead bricks. Lead time for differential builds are usually 2-4 weeks.
