Hadley ride height control valves

[Ziegelsteinfaust]

I am debating putting air ride on my Willy's wagon since the coil overs I need are $1500 dollars or so.

So it got me thinking of air ride on the TTB, and doing quad shocks. As the factory bucket has it but leaves no room for a bag effectively, but I have the other parts nessacary. Kind of one and done issue. No more helper bags or buying springs to get it just right. I can shim the bag easier till nirvana is found.

Has anyone used a Hadley type valve to automatically keep the ideal ride height?

They seem like a good idea since the can adjust automatically, and they seem to have a good life span on big rigs.

Only issue I can think of is off road where I may want to shut air off to the valves to keep them from adjusting all the time.
