The factory Ram 5500 front coils and shocks were replaced with Kelderman air springs and adjustable Rancho RS9000 shocks. In the rear the leaf springs were ditched in favor of a Kelderman link-style suspension with air springs. The air springs are filled automatically with an on-board compressor that also feeds air chucks at the front and rear for filling tires or do any other compressed-air chore.
