Goodyear air springs, also known as suspension air bags, can be purchased online from a variety of sources such as Dayton Air Control Products or SDTrucksprings.com. However, Goodyear does not manufacture SRS airbags, the sort used for passenger impact safety.
Air springs or suspension air bags are suspension cushions that use compressed air in a bellows-style device to provide smooth suspension in the heavy vehicle industry such as freight shipping or mass transit. Goodyear manufactures a variety of such devices most of which are readily available for online purchase.
SRS airbags manufactured by other companies can be purchased online from sources such as the Airbag Center, Autopartsonline.com or even using an eBay search.
