Chrome Valve Stem for GM TPMS System
Chrome valve stem for GM TPMS system reolacement for 504.
Fitment and specs
- Chrome finish valve stem
- Made for GM TPMS systems
- Direct replacement for the 504 valve stem
Valve stem replacement happens with the tire off the wheel, so the easiest time to swap this in is during a tire change or repair. Handle the TPMS sensor gently while the stem is out, then air the tire up and check around the base of the stem with soapy water to confirm a clean seal before driving.
Common questions
Will this fit my GM TPMS sensor?
It is built as a replacement stem for GM TPMS systems, specifically for the 504 stem. Compare it against the stem you are removing; if yours matches the 504, this is the correct part.
Do I need to replace the sensor too?
Not if your sensor still reads correctly. A corroded or leaking stem is often the only fault, and swapping just the stem keeps a working sensor in service instead of paying for a whole new unit.
