An air ride suspension system is not as complicated as it might sound. Air ride suspension system simply replaces a standard steel spring with bladder or bag of compressed air. The resulting effect is a much higher shock absorbency ratio to provide a smoother ride to the truck and therefore the trailers cargo.

An air-ride suspension is a kind of suspension that supports the load on air-filled rubber bags rather than steel springs. Compressed air is supplied by the same engine-driven air compressor and reservoir tanks that provide air to the air brake system.

"Air ride" suspension, as it's sometimes called, offers several important benefits that may be useful to drivers interested in luxury cars. The primary benefit is ride quality: Vehicles with air suspension are often said to "glide" over bumps, while traditional steel spring suspension can cause a harsher ride.

Air ride equipped trucks use an air ride suspension system instead of conventional steel coils or springs. This suspension system uses an air compressor that provides compressed air into airbags that act like springs when properly inflated.
