8 POINT GREAT

Jeep XJ, YJ, or TJ/LJ model is a Ford 8.8.

- Christian Sturtz

AN excellent option for an upgraded rear axle in a Jeep XJ, YJ, or TJ/LJ model is a Ford 8.8. Ford 8.8s are found in 1995-2001 Ford Explorers and Mercury Mountaineers. Other Explorer variations through 2005 sported them as well. However, you will want to do your research and make sure you know what you are buying. (Figure 1)

Why is an 8.8 a great axle to swap into a Jeep? For starters, they have larger ring gears than are available in the XJ, YJ, TJ/LJ models. The axle shafts and wheel bearings are also bigger. They have large 3.25 axle tubes that are .250 or .188 wall. They come factory with disc brakes, internal emergency brakes, and their width is close to Jeep width. They are available with factory limited slips and 4.10 gears; though other gear ratio options are available. Bonus, there is huge aftermarket support!
