    I have a 2000 Pete 379 with air trac suspension currently working on conestoga flatbeds. The fifth wheel sits at 51’ from ground after switching to 22.5s from 24.5, I’ve also lowered the bags to the minimum where vibration won’t set in the driveline.
    I’ve already hit a 13’6” bridge once when I had 24.5s on. Does any one know if there is another suspension i could switch to lower the truck, without doing any modifications to the frame
