Air pressure control valves for air bag suspension?

Today at the Quartzsite RV show I was talking with a rep from Hendersons Line-up out of Oregon. I was considering a heavier sway bar for the front of the motorhome.

I told him that I didn't like the way our coach rocked back and forth when going out of driveways and other uneven surfaces. He showed me some kind of flow valve that is spliced into the existing air line to each bag. Apparently this valve(about 2" long)slows down the rate of air flow when the bag compresses in a turn or when the coach leans on an uneven surface. Also, it slows down the air flow coming back into the bag as is returns to its normal height. He said that it is quite effective at stopping the rocking back and forth motion.

I have never heard of them and am wondering if anyone here is familiar with them or has used them. If so, do they accomplish what the rep says they do? BTW, they were $795 installed.

Thanks for any input in advance.

    Well, I don't know about the valve that Henderson's have but I have those installed by Source Engineering and I can tell you that those valves do make a difference.

    They do make a difference in the suspension so you have to make a decision

    Had them put in at an FMCA Rally years ago with good results. A couple of years of later we went to their shop in Grants Pass and had an assessment/test drive done and a list of suggestions in order of best result for least dollar. Do as much as you want. We went with their recommendations, which included NOT doing certain things until we had driven a bit to see if we wanted to spent that extra money! Only have good things to say about Henderson's Line Up

    Like dons2346 I also went to Source Engineering and had the Comfort Control Valves installed, made a difference in the ride, Valves $100 each, labor $100.

    While there I also have the wax valve install, what a difference in coolant temps.

    Did they stop the rocking back and forth going in and out of driveways? Also, is there less leaning of the coach going around curves on the highway?

    Thank-you...Don

    The valve was invented by Henderson and is sold by a number of folks. They are supposed to be very effective but I have not talked to anyone other than Henderson about them.

    I had similar valves installed on my Tiffin Zephyr and they reduced the rocking going in and out of driveways by a great deal.

    I've heard some mixed reviews on them, but most people say they do make some difference. I think from what I've gathered it depends on the coach, length, and overall chassis.

    Thank-you, this is what I wanted to know. Thank-you to everyone else that has commented and is familiar with them and their effectiveness.

    I hope to hear more comments from people that have them on their coach and how much of a difference they make in controlling the rocking motion...Don

    Just go to a Peterbilt dealer and get a Valve for a Pete. They work best, last forever and are the simplest one to install.

    Well, that depends on how fast you go over the curb. The valves don't stop everything but slow down the actions and yes they do eliminate some of the roll going around curves.

    If you want the ultimate system, you need to install the Active Air system from HWH
