I have qbags and now new kyb shocks. Qbags manual says max 150 psi I am wondering would lifting to coach with 150 psi be alright for the shocks?
Reasn I am wondering is that It annoyes me that I have to let air out of the system before I can rise here when entering a strech of bad road, bumps etc.
I now have 90/120 pressureswitch amd figure a 110/140 would solv that problem. Just dont want to ruin my new shocks

Normal driving pressure is 80-90 psi. Now if I want to rise the coach the pressure in the tank and the bellows equals out somewhere between the 90 and 120 psi ( probably just above 90) andnothing happens before I let out air so the pressure comes below 90 psi and the compressor starts
I guess one could fix this electricaly as well
Wonder how much is needed to bottom the shockes

Ofcourse. I forgot that I do not have the original adjustable pressureswitch, but one of these modern nonadjustable ones. Getting a other switch might solv the problem.
Still wondering how much pressure might bottom the shocks. Depends on weight , I guess

When you raise it to the max, the shock are stressed, but it is the bolts
that will be get a side moment applied. make sure they are tight.
Both KYB and Bilstein have a special bolt to handle it, however one need to
go gentle when it is at max. travel either way.
Bilstein had problems with the unit coming apart and would not warranty
them by declaring abuse.
I have yet to see that problem with the KYB yet as they are constructed
differently.

Jim,
What is the "Dead Band" on the pressure switch? I tried to adjust the pressure on my switch a couple of years ago but couldn't figure out how to do it and gave up.

You need to adjust the Dead Band on the pressure switch so you need to not
decrease the pressure as much.

Going back to your original question, the stock airbags will require about 120 psi to reach full extension for a fully equipped 26 ft coach. I don't know what the effective area of the quad bags is for comparison, but hopefully a well engineered product will have that data for comparison and you should ask your supplier. What you need to think about is that at 120 psi, you are basically supporting the coach and not applying any excessive force on the shocks or mounts. If you go above that, the shocks will start to experience increased loads. The EL II system is designed to max out at 120 psi and cannot exceed that pressure for a reason.

The switch has adjustment for max pressure so it will open the circuit when
it reaches a preset high pressure.
The dead band is built in and also adjustable so that the compressor will
not kick on when the pressure drops slightly.
The one we sell need to go down to40-50 psi before the compressor can come
on.
That is when it is adjusted for the highest dead band pressure.
I think we need to look for another style that will have a higher low band.

Our Quadra Bag System reaches Max height at 135 psi on an average 26 ft.
coach.
The Harrison 4 bag unit needs 160 psi and even it will not raise a
stretched coach, that's when Jim Bounds came to us to come up with a unit
that can handle additional weight at lower pressure and also hold up
without frame distortion.
We based our design from Ken Rose unit and acquired the rights to use what
design he had and had Rick Flanagan redesign it for us.
