What Kind of Valve Stems on XC ISB?

[DWM]

Folks, I have a coach bulit on a 340HP Freightliner XC Chassis. The coach is in service now, so I cant look myself... what kind of valve stems come on the wheels? These are non Alcoa rims... just steel. Reason for asking, is I want to order a Pressure Pro system today, but hear there is an issue if the stems are not metal.

Thanks

That is true DWM, there have been a few stories of problems with rubber stems cracking when used with sensors, due to the centrifigul force. I would install steel stems if you don't already have them.
I don't know what your coach came with, but it shouldn't be to difficult to check them yourself.
