valve stem extenders what a joke

so i have been dealing with these valve stem extenders,real dualls inside tire the extenders come through outer wheel and there is nothing holding them.they just flop around there.i cant believe they sent this out this way.called alcoa today and they said take off and throw away? they have a solid stem that you screw on valve stem and there is a rubber boot that goes in hand hole and solid stem goes through rubber boot.this only makes sense.i wonder if ford did this or forestriver???????????? this is a stabilizer that works.

Same here Alcoa 22.5's and those extenders are a joke. You have to have three hands. One to hold the floppy extender, One to press the compressor valve onto the extender and one to push the lever on the compressor valve. I finally gave up and just electrical taped the level down.

Plus one of my extenders doesn't work. Neither of my compressor connections or either of my two pressure gauges will work with the one. I can shove a screwdriver in there and have it release air so it is connected.

The Ford chassis maintenance manual says to rotate the tires anyway. So I'm going to take it to the local truck tire center and have them rotated and have those extensions replaced with big long valve stems.

I hope your alcoa have the clear coat finish ...my last mh had them but they were the cheapie alcoa's and I had to polish those suckers twice a year and man what a job..they oxidized and went dull real fast. The ones on our new Georgetown wre supplied by Ford and they are highly polished Chrome...no more aluminum for me and just a quick wipe and they shine lilke the dickens.

Can't speak for the Class A's, but on the Class C Duals, we started using a product called "Air-Flexx". The problem with most extenders is that they are "pressurized", when you screw them on they open the tire nozzle and move the seal point to the end of the extension. If they flop around rubbing on the rim and break...then the tire goes flat. If they get loose, the tire goes flat.

The Air-Flexx is rigid so it needs no clamp and it is not pressurized...there is a metal shaft that goes from the end to the tire nozzle. When you push the metal shaft, it then opens the nozzle on the tire stem. You can cut it in half and the tire will not leak. Our blown tires due to low pressure and warranty claims on leaking extenders is now non-existent. They're made in Germany, but when we started using them they set up a US distributor.

Glauch Air-flexx

Petey, Take a look at your wheels. On my 2007 the inside dual is on a steel rim with the Alcoa on the outside. The problem with the kit is it comes with a straight extension as the Alcoa wheels normal have a 90 degree stem. The steel wheel has a stem at about a 24 degee angle. An entention with a bend close to the attachment point may work but the one I got was bent in the middle and you can not get it to line up correctly. I have tried to bend a 24 degree extention to fit however the centers between the bends was a little too short but it is the right form for refrence. Let me know how you make out as I maybe missing something. Will work on posting a pic

Pic shows standard Hal Tec 24 Degree Entension and the one I modified. It is close but needs fine tuning shown just for clarity of the situation.

Interesting this topic came up. I have a 2007 378TSXL and all but one of my extenders works. The one that doesn't is the passenger side rear inside dually. It has a flexible stem that's worthless and doesn't work at all. I can't get a reading on a gauge and nothing happens when I push on the stem. I put WD-40 on it to see if that did anything and it doesn't. I might try putting a little air in from my compressor and see if that releases anything??? I think the pressure is fine right now so I don't want to add or take out a lot of air since I can't get a reading. I could error in either direction and wouldn't know. Rubber mallet seems to bounce and sound the same as the outside dually however.
