Review on 🔧 Enhanced Black GM Original Equipment ACDelco TPMS Sensor 25774006 for Tire Pressure Monitoring System by Brian Lee

This is the best price I could find for a Delco AC sensor for my GMC Envoy so I bought four and received them within three days. I thought as the price was much lower than others they might be old (not good due to a non-replaceable battery) but that is NOT the case as the date code told me they were made less than 1 year ago. Some have mentioned that mounting nuts are not included, well I bought the kit from Autozone for $1.99 per wheel so only $8.00. The reason not to reuse an old nut is that aluminum on aluminum corrosion can damage the nut or shaft if it is removed and there is a captive seal in the nut which also usually breaks. Just make sure you get a fitting kit (some call it a service kit) ahead of time, as the tire shop will charge you $5 per wheel or more.
