So i started installing my gears myself(i know
) on sunday. Had a few things to do so i got off track and just finished them up today. I used Motive 4.10s and bearing install kit with valvoline fully syn 75w90 gear oil with Ford friction modifier. All i can say is this should have been done a long time ago they pull so much harder than the stock gears. Just now i have to get used to redline coming so fast and the speedo being off. So far i have about 100 miles on the and have ZERO whine. Feel free to ask any questions or make any comments.
