Full air ride modification
Ok friends, this is a project that I have been looking forward to for a few months now. Took delivery on the 2018 F550 in August of 2018 and have been using it for a daily driver since then. It was t...

Wow, so you have to remove the original suspension mounts for the Kellerman bits to work? Looks like quite a project.
That is the reason I went with the Autoflex rather than the Kelderman. The Kelderman install instructions show pictures of cutting torches and air chisels. The Autoflex is strictly bolt on, and can be returned to stock at any time. Also the Autoflex feeds the load into the frame at the same points as the springs (where Ford designed them to be) while the Kelderman does not. Not sure they make a Autoflex for a 550, but it works well on my 350.
I have to say you are wrong there!!! Ford pop riveted the top stoppers for the overload springs to the frame, I just used a zip cut to cut the tops off the rivets at the bracket and punched them out through the frame, no torches needed to cut any holes or anything like that! Also wrong about the use of existing holes, the Kelderman system utilised all the existing spring hanger bracket holes for this system (Where Ford designed them to be) I Had to drill a few extra to bolt on a strut bracket. Yes it may be a bigger job to install but there is no question in my mind about the structural integrity of the system that is why I went Kelderman. The way I see it, they are the leaders in the market for air ride systems. You have to understand that the 550 has a 12,000 lb. payload capacity and a 30,000 lb. trailer capacity, I am sure that it is engineered for a safety factor built in to those numbers.
