These valve stems were purchased for my '19 Durango R/T. They fit perfectly and look great compared to the factory plastic caps. They also go all the way to the rubber so you don't see any brass threads on the stem. They look like they have a gasket so they can hold air if the valve leaks. I haven't tested this but I'm sure they will be fine. They are very light, most likely aluminum. I'd be afraid to strip the paint off with the included wrench/keychain so I don't twist it too tight. If you're worried about someone stealing them, just let them steal. The stem will be damaged more if you make it difficult or impossible to remove.
