I assume you are referring to the tires on your truck and not your trailer.
In the GM model 1500 truck you probably have the TPMS sensor like below:
This TPMS snap-in valve stem/ sensor lets you unscrew (D) and just replace the rubber valve stem (C). It's a lot easier and cheaper to fix, when the stem itself goes bad, as compared to a TMPS sensor/stem that is all metal (which have a habit of the valve core seizing in the threads). It also allows more flex, and won't break as easy as the all-metal TPMS sensor/stem. You just attach the new rubber stem to your sensor body. We buy these in case quantities.
Finding a clamp-in metal stem that is going to attach to the sensor body, is easier said than done. What you will want is a VS-925C. You'll most likely need to get them off amazon or such and take them with you when you get the tires changed, as most dealers won't have it....or even heard of it.
Here it is below. Hope it helps.
