Does anybody know of a rebuild kit for the Power Level II air bag control. I've isolated my leak down to the valve itself.

Skip,

AFAIK you have three choices:

New ones from JimK:

http://www.appliedgmc.com/prod.itml/icOid/685

Rebuilt ones from Dave Lenzi:

And bidding on these on eBay:

First you'll need to identify your valves.

GM did NOT produce a "Power Level II" system. Some replacement valves came with a plate that stated "Power Level II" and I suspect that is what you have.

If your valves are not original, I do not think that the lit from JimK will fit. If they are original, the kit should fit, but I haven't heard of very many getting lasting results from a rebuild. Your results may vary.

As I have not rebuilt any power level valves... someone else will have to provide guidance on that.

I presume you are talking about the after market dash valves that were supplied by J R Slaten. I believe they were made in Sweden or there abouts. They are nice valves almost bullet proff. I would contact J R or Jim K can probibly help.

Roy,

The valves are made by Swagelok; headquartered in Solon, Ohio, U.S.A.

I used their valves quite a bit when I was building ground support test stands for Project Apollo hardware.

I found them to be bullet proof! ;-)

Rob M.

Well this is still a very individual choice, like most everything on the GMC. Simplicity - yes. Final answer - that is an individual decision. Complete function - no, as it does not automatically adjust the ride height. It is a very interesting option that may have appeal for some GMC owners.

What I would be interested in seeing is a line of GMC's, side to side or end to end, all with the wireless system, how many coaches would one transmitter effect? <GRIN>

Encryption is a wonderful thing

Just add schraders and you will have time to make choices

G'day,

IMHO this system is a fine replacement for someone that has a messed up ELI or ELII as long as they are aware that:

1) You will loose the automatic ride height control system as this system is NOT an automatic leveling system; it is an automatic
pressure control system. As you drive consuming gas the weight of your GMC will decrease and this system will not compensate for it.


2) This system will only deliver 100 psi to the bags, if it takes more than that to raise your coach you will have to fit "bag
risers" that raise the bags which in turn will effect the static height adjustment.

According to the proponents of this system neither of these items makes any difference which I believe, however, people considering
the considering installing the system should be aware of them.

Personally I follow the KISS principle and love Double Trouble's and The Blue Streaks Powerlevel System with no electronics and:

1) JR's dash valves
2) Viair 280C air pump
3) All new nylon color coded air brake tubing
4) All new Parker Hannifin air brake fittings
5) Two rebuilt height control valves from Dave Lenzi

Regards,
Rob M.

that is true, except it works for:
quadra bags

oem bags
markbags
Hensley bags
southland bags

I never understoodd why people want to cripple features like automatic leveling.

Mine will air down slightly every 2 hours or so of driving as fuel is used in the tank. Every time I fill up with fuel and drive off, I hear the pump kick in to raise the coach automatically due to the added weight. I also notice that is lets some air out after I dump the black tank. I do not know how much it takes to trip the leveling switches, but one time I stepped into Arch's coach and the compressor kicked in. He said it was because I added 200 pounds to that side. He left the system energized for some reason when the coach was parked.

Why cripple automatic leveling or engine preheat of the hot water tank?

but

fixing the air system, is going to become very hard , expensive, or almost
impossible in the near future

I find that 4 out of 5 gmcs are running or schrader valves, which is just
not acceptable.

nice to have some choices
