Review on 🚗 Chevrolet GMC Rear Backup Parking Assist Sensors Set of 4 - Replaces 25961317 - by ENA by Russ Montgomery

I removed my old parking sensors and plugged them in to see which one was faulty and all but one were faulty so I replaced them all and no problem. Now I have an old spare just in case. 10 times better than going to GM for new ones. Installed theses on my problem avalanche. Great replacement.
