Don't waste your money on this! Two of the four sensors failed, now I have to take the tires back off, make an appointment, go back to the tires and wait 3 hours. Do yourself a favor and just buy the factory sensors. I used to do wheels and tires and those sensors are a joke. Get what you pay for I guess! I should have known Update: After struggling with sensors not picking up any of the relearn scanners from 4 different tire shops, I went to Ford and spent $250 to replace 2 sensors. On the way home, the sensors picked up the truck and started working after about 60 miles.
