Quality gearset
06 F150 4WD rear diff ~ These were purchased to replace original r&p due to high mileage wear. Went ahead and paired this set with an Eaton TruTrac, replacing the OEM limited slip diff. They run cool and quiet when setup properly. I've been running Motive gears for a very long time with zero issues.
