So, you did need sensors! Ah, ha! I knew it!
please post the results of installing and matching them to your SS.

 

But not for my aluminium rims.
As you stated earlier.
Again, I stated this with a question about frequency and who cares about price or why some are higher than others.
Don answered the question.
So thus I bought Ebay stuff.
Now how long the batteries last in them I really don't care.
Why ?
For $8 each they are throw a ways when they fail.
Sorry that's $8 US, not Canadian.

Just to inform people, when I bought my aftermarket wheels I bought sensors from Walmart, installed them and used the relearn from the GM manual and everything is AOK. (That's NASA talk).

 

Aluminium or steel you still required sensors.
I figured those prices were in US Funds, no need to apologize.
The term A OK was coined in 1952 , by advertisers , long before NASA

The less expensive sensors, may have
inferior rubber compound in the valve stem
inferior metals in the stem threads
inferior batteries, not lasting as long as OEM parts
However as you say they are throw away parts at that price.

I looked at that EBay vendor, they don’t ship to Canada so I ordered these for the BlackSwan’s summer rims

About $11.99 each CDN and that’s $7.44 USD, so a great deal , even if the batteries only last 4 to 7 years.
3 of the 4 OEM sensors on the BlackSwan have been replaced and it’s only 8 years old.

My stems in the rims are still OEM
I'm just going to put the sensors on them.

 

The sensors I ordered arrived today, I’m going to have them mounted in a set of summer rims and tires for the BlackSwan .

 

Metal VS Rubber .....

2 possible reasons for Metal are, "Looks and Safety" under Higher air pressures and High performance stresses.
When tubeless tires first came out... the Rubber valves were larger and (fatter) with a bigger wheel hole.
I have seen where they blew out of the wheel upon a Hard impact and under the right conditions.

Schrader made Metal valve stems back in the 1960's
We used them mostly on Tubeless Truck Tire applications.
Some Custom car owners liked the Looks.

Silverfox

 

These hidden valve stems were cool but a pita to check pressure and open in rainy weather, I suggest not using these in the snow.
Thankfully they aren’t TPMS

 

Which part number is replacement for original if I got from rock auto thanks

 

13598771 is the GM OEM part number
