Yikesai 4X Backup & Reverse Sensor Kit, Rear Parking Assist Sensor Compatible with Ford F150 F250 F350 E150 E250 Escape Explorer, Lincoln Mercury Mariner, Replaces 684-029 3F2Z-15K859-BA

These sensors were cheaper than the same parts at a junk yard (and the junk yard parts were all no good). These do NOT exactly match the appearance of OEM when installed, so even if you have only one that needs replacement, you'll want to replace all 4 if you care about them matching in appearance. They are not hard to replace and fit perfectly with the OEM housing for my 2006 F-250. They fixed my park assist system and work great now.

It fixed my problem! So much cheaper than OEM and works the exact same!

Fixed the faulty backup sensors on my used 2011 super duty. Installed pretty easily. I only replaced the bad ones and kept the extras for spares. It's actually easy to tell which ones are bad. You shift into reverse to activate them and if you go the back of the truck you actually here them repeatedly clicking if they're working. Replace the silent ones and you're back in business. Easy peasy.

Gave 4 out of 5 stars because 1 sensor didn't work as well as the others. I installed all 4 sensors in my 2006 Ford Explorer to replace 1 defective one. I did this so they would all match. However when I tested them, 3 of them would beep and then beep constantly when I was moving my hand by the sensor, 1 of them only beeped a few times and never increased the frequency the closer I put my hand to it. I replaced that with 1 of my old ones and it worked fine. So overall these work, but make sure you check them before putting the bumper back together!

As good as OEM at a better price.

I needed to replace a parking sensor on my 2015 F-350 Super Duty. I figured this would be a simple 5-10 minute install, especially since the old sensor came out so easily. WRONG. The new sensor(s) come way too long, so they won’t even clip to the wiring harness with extreme force. I tried 3 of 4 in the pack, none fit, so I was about to give up and send them back… I decided to sand it down a few millimeters and got it clipped in! I didn't think I’d need my random orbital sander to get this sensor installed being this part claimed to fit F350’s of this year. Be cautious buying this product. Consider a different product or buy OEM. Once installed, it seems to work fine — This and the fast shipping are the only reason for the 2 stars.

Fit perfectly! Now my backup sensors work as they should! I don’t feel like I’m backing without assistance. New backup camera and sensors, it’s like having a new truck!

Decent quality, plug and play, easy to swap. But I believe one of the new ones I got doesn’t work sadly. Can’t hear the ticking noise like the others.
