Question:
If I plan to put the tireminder dually extension kits on before these sensors, can I use the passthrough sensors? The extension kit Im talking about is so that I can secure the braided extensions to the lugs.

Hey Tom! Yes, you can physically use the flow-through sensors like # TST-507-FT-6-C with a braided dually extension kit. However, it’s not something we typically recommend.
Those flow-through sensors are larger and heavier, and when you add that weight to the end of an extension, it can put more strain on the fittings. This increases the chances of leaks over time. For that reason, the cap-style sensors # TST-507-RV-6-C are a better choice for use with extensions.

I have a class a, Forest River fr3. It has steel rims with simulators. I'm worried about access the the inside dual if I need to add air. It's darn tight in there.
