I tried and tried to convince myself to buy a suspension that was already designed, built, and ready to install. Nothing that I could find fit the bill. I decided on an airbag suspension, and the only one I could find out there was from Lesu. Can't be putting Chinese junk on a fine piece of German engineering! I was left with only one option... design and build it myself. This project is already turning into more than I bargained for, but I wouldn't have it any other way. Came up with this design based on the Peterbilt Low Leaf air ride suspension. The parts will have to be 3D printed, but with the high quality of metal (yes, I said metal!!) printing, I am not worried about putting poor-quality printed parts on a high quality model. Lots more to do!
