Air springs, also known as gas spring or pneumatic springs, are a type of vehicle suspension system that use pressurized air to support the vehicle's weight and absorb shocks from the road. They consist of a flexible, inflatable bag made of durable materials such as rubber and polyurethane, which is filled with compressed air. Air springs are commonly used in commercial trucks, buses, and trailers, as well as some luxury cars and SUVs.
