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.

The air suspension system effectively absorbs those bumps and thumps on the road, reducing the risk of cargo shift and damage during transit. Air ride trailers are often used to transport items such as electronics, pharmaceuticals, and delicate equipment.
