They vary. I have had three different types depending on the wheel. Two were 90 degree and one was 45 degree. The lengths I think were different also. I think the reason is two coaches had aluminum inner wheels on the drive and one had steel inner wheels. I never considered looking at the tag and steer to see how they were set up.

One wheel had the valve stem mounted on a 45 degree surface and the other two were on a surface parallel to the ground. I think.

My inside dual stems look like this Joe.

That’s what mine looks like,

But I think they bent it to 45 degrees when they replaced it so I can air them up.

So I suported it and crawled under, because I could not

see around the centramatics. Jon it has steel wheels and Tom you

and Tim were spot on on the straight stem. thanx I wont remember

this a month from now

Mine too are like Tom’s. I think they are made out of brass because I bent them by hand a little bit to optimize air chuck access. Steel inner wheel.

I am installing Crossfire 120 PSI air pressure monitor and fill system. One set of hoses mounts on your outside tire and continues on to the inside dual axle tire. Air both tires from the ouside tire. It has a monitor system on it that will show if the pressure is right, high or low. Best thing I have seen. It’s about 130 bucks for both sides.
