Yukon ZK F8.8-B Ford 8.8in Overhaul Kit for 2009-2010 F-150/2010-2014 Mustang

Vehicle Fitment

• 2009-2010 Ford F-150 - solid (live) axle, Ford 8.8" rear differential
• 2010-2014 Ford Mustang - solid (live) axle, Ford 8.8" rear differential

Fitment Notes

• Fits the earlier-generation Ford 8.8" differential (10-bolt cover) used prior to 2015 - not the redesigned "Super 8.8" (12-bolt cover) introduced on the 2015+ Mustang and F-150, which requires a different kit
• Confirm your F-150's model year and differential generation before ordering, since F-150 differential specs changed more than once across this era
• For solid (live) axle applications only

Product Description

The Yukon ZK F8.8-B is a complete master overhaul kit for the Ford 8.8" differential found in the 2009-2010 F-150 and 2010-2014 Mustang - the earlier 10-bolt-cover generation of the 8.8" that predates Ford's 2015 "Super 8.8" redesign. This kit bundles everything needed for a full rebuild into one part number: carrier and pinion bearings and races, pinion seal, a complete shim kit, crush sleeve, ring gear bolts, and the thread locker, marking compound, and gasket needed for proper reassembly.

Built with Koyo bearings, it's designed to restore correct bearing preload and gear backlash after normal wear, or after a gear ratio change or locker/posi installation. Because Ford revised the 8.8" more than once across F-150 and Mustang production, confirming your exact model year and differential generation is important - a Super 8.8 unit from a 2015+ Mustang or F-150 uses a different bearing case and is not compatible with this kit.

This is a rebuild-support kit rather than a ring-and-pinion set, so it's meant to be paired with either your existing gears during a straight overhaul or a new gear set if you're changing ratio. Installation requires full disassembly of the differential and proper backlash/preload setup, so it's best handled by an experienced DIY installer or a differential shop.
