Hey guys, I've been toying with the idea of installing air bags with levelling valves like the semi's have. I know there's a minimum psi for the air bags of about 10psi. Is there any valve that's not computerized that has a minimum level or any way to install a bypass that disables the valve under a certain pressure? The only way I can see it working is to set "level" to be a smidge higher than empty, but that would harshen the ride unnecessarily. I realize I don't need to do this, and I realize it's extra work and probably a waste of money, but I still would like to consider it. I'm just wondering if anyone has any ideas I haven't thought about yet. Thanks!
