I used those on my srw truck and use them for car tires when I mount them myself as I have a bunch of those valve stems. I would not use them with an extension. if you want an extension stay with a clamp in valve.

Here is the information from the tra book . 80 psi max and no metal extensions .
This is the same one I asked about. I am trying to come up with valves to extend from my rear INSIDE wheels (Dually) through the outside wheels so I can adjust the air when I need to.
Do NOT use extensions on TR600HP valves PERIOD. End of discussion.
If you want to use extensions on an inside dual, you MUST use all metal clamp in stems sealed with a nut and a grommet, not with hope and a prayer like snap in valves.
I have bolt ins right now because an aftermarket TPMS is in my future and I was told the stems needed to be steel because of the added centrifugal force of the TPMS caps. I wonder if those ones from Amazon would work?
No, the ones from Amazon won't work as advised if you want to hang more weight on them. A TR600HP is a TR600HP, whether it sold by Amazon or made by Dill. The TR600HP is a trade number that represents a construction and specification standard for a tire valve, not just one company's model number. Ford has been using TR600HP snap in metal core rubber bodied valve stems since 1999, and after many valve stem complaints, blowouts and even a recall on the heavier duty duallys with these stem, Ford soon switched to all metal clamp on valve stems on duallies (I think that trade number is VS962C for F 350 duallies, and VS902K for F450's / F550's / F-53, and VS938F for E-350 / E-450 cutaways).
Since Ford OEM dually rims of this era all have .453" valve holes, any TR800HP stem rated for 100 psi will not work either, as they are for rims with .625" valve holes. Besides, it isn't the pressure rating that is the problem. It is the construction of the external tire valve body itself that is not conducive or designed to stabilize added on weight from extenders or externally mounted aftermarket TPMS systems.
If any one is planning on screwing extra stuff onto the ends of their tire valves, it is highly and universally recommended that snap in valves be avoided and exchanged for true all metal clamp in valves.

When I stated they worked great, I was comparing them to the bolt clamp style. I've never had an issue reaching the inside dual to check pressure. TPMS would be nice but I'm cheap LOL and have other area to spend my money. Are you planning on using a special brand with stand alone monitor?
When I have my wheels off I plan to break the bead and install longer Clamp in stems. Before I put them in I'll bend them as needed. I think TR574 is the 5" one but the rubber grommet is for a .625 hole so I will have to swap the grommet. I looked at some today and it is grommet RG54 for a .453 rim hole. TR416 or TR416s is what came on my dually. If you buy them in the store they come with both the .625 and .453 grommet and is sold universal.
I would think TR416 (commonly called Corvette clamp in valves) would be too short. I clarified my post above to distinguish between F-350 pickups, F-450/550 chassis cabs, and E-350/450 cutaways as far as clamp in valve stems go. All the ones I listed are longer than the TR416.

I am planning on the TPMS for a travel trailer but I figured might as well do the truck at the same time, yes standalone monitor. Several brands are in consideration, I am researching on the Airstream forum getting people's input.
