Air Suspension

Air Suspension is a type of automotive suspension that uses air springs instead of conventional steel springs. Computer-operated vents on the air springs, suspension sensors, and an onboard air compressor allow the system to maintain ride height and vary the suspension's ride characteristics.


Air Spring

An air spring is a rubber and fabric bladder that holds air pressure to support a load and isolate passengers and cargo from the shock of motion caused by road irregularities. As the air pressure increases, the air spring can support more load while the spring rate increases. The larger the air spring, the greater the maximum load it can support.
