Trailer TPM Sensor size


Recommended Posts

Hi, New here but been lurking awhile. Getting ready to trade by 2017 2500HD WT for a 2020/2021 LT with advanced trailering system. My horse trailer has a 7/16 hole for the valve and I haven't been able to find the size of the sensors (PTT) . Seems like a good price to order with the truck as opposed to aftermarket / GM Accesssory.

 

I have read quite a bit here about the setup so as a followup, is it worth it overall as I am only going to the LT trim to get the advanced trailer package.

 

I put approx. 30K on the truck each year and tow the trailer for probably 20-25 of that.
