Starting in 2010, Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Due to this, installation will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please see drop down option above.

You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.
