It replaces the traditional steel spring with a flexible rubber bellows that supports the load and adjusts ride height via air pressure. This air spring is typically replaced when it develops leaks, cracks, or fails to hold air, causing the trailer to sag or ride roughly. It is a direct fit for many Watson & Chalin and Ridewell trailer suspension systems commonly found on dry vans, flatbeds, and refrigerated trailers.
