    I am changing my 8 bag Air Glide 100 to a dual leveling valve setup. I have a straight truck so the box makes it a real P.I.T.A to trace the lines, otherwise I would just look to see how it is setup now. I 've drawen how I think it should be, but I am not certain. Can some one please tell me if this looks right, or am I way off? Mainly I am wondering about my connections at the dump valve.

    most people go from dual valve to a single because the dual systems are a pain in the *** to keep in adjustment

    Assuming the swithes to the left of your diagram are the electric switches, yeah that will work. You could also run two lines out of your dump valve, one the the front axle and the other to the back. Or better yet, after the dump valve, put in a quick release to T off to the front and back.

    If you wanted to stay with one leveler just T it off and add the dump valves after the T. Do not buy the cheap plastic POS levelers! They are a PIA to adjust. Buy the good metal ones, they have a screw for fine adjustments.

    Your schematic looks good. When you adjust dual system valves, you have to adjust one side at a time. Start with adjusting one side to the proper ride height with the other side disconnected. Then repeat with the other with the first side disconnected. Always adjust to the proper height on the up-travel with the brakes released and wheel blocked.

    Yeah, I got the metal height control valves. I see you can use them as long arm, or short arm. I would assume the short arm will be more responsive. Not sure which way I will mount those. Thanks for the help guys.

    I have worked with them and they can be a pain. but will help with uneven load swaying. u can just t off the dump switch no need for 2 switches. i have used this set up on rv to help with the wanderring issues.
