Description
Install or Rebuild. Don't be caught without the seals or hardware you need when doing your gear swap or rebuild. An Install kit has everything to make installing new gears or rebuilding your 8.8" rear easy and painless.
Extra Insurance. If you're installing new gears, an Install kit is extra insurance against future problems. Any Mustang can benefit from fresh hardware in the differential to ensure your gears perform flawlessly. However it is highly recommended to add this kit to your new gears for any Mustang with over 60,000 miles, since your differential's hardware is probably worn down and you can combine labor costs to save money.
Complete Kit. This kit has all the components of the Installation Kit, including pinion seals, gaskets, hardware, marking compound and brush, and even Loctite. It is the same as the Bearing kit without bearings.
Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this you will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please see drop down option above.
Application. This Install Kit is designed for all 1979 to 2014 Mustangs with the 8.8" rear end.
