Wanted: 4-GM Trailer Tire Pressure Sensors (TPMS)


Recommended Posts

My 2020 2500HD Denali Duramax came with the towing package and had 4 TPMS sensors in the glove box specifically for adding to the trailers.  When I replaced the Chinese tires on the trailer I had these installed.  I purchased an activator tool from Amazon for about $15 to sync each tire TPMS on the trailer to the truck.  Worked first time.  A great feature to monitor not just pressure, but temperature as well.  I suspect these can be ordered from GM- but may be expensive.

I actually have the tool from Amazon due to me changing from Winter to summer wheels on my truck.  The GM sensors are much more expensive purchased from the dealer than when ordered with a truck.  Only $50.00 option if ordered,  Was hoping to find someone with he GM ones they didn't need and wanted to sell.  I can purchase aftermarket for around $80-$90, but was hoping for real GM, not aftermarket.  Thanks.
