Abstract: This invention pertains to the end attachment components used on all air springs in the automotive and light truck suspension market. Previously these end attachment components have been composed of one or two threaded bungs used for mounting the finished product to its application and a single ¼″ or ⅜″ NPT port used to pressurize and depressurize the air bellow. This invention incorporates the use of a single larger port in sizes including but not limited to ½″, ¾″, 1″ and 1½″ NPT. This invention also incorporates the use of multiple ports in sizes including but not limited to ⅜″, ½″, ¾″, and 1″ NPT. The use of larger or multiple ports allow the user to pressurize or depressurize the air spring more rapidly.

Abstract: An automotive wheel suspension comprised of a shock absorbing strut located within a retrofit air spring which is located where previously a standard coil was located. The air spring includes a single, double, or triple convoluted bellow comprised of a rubber bellow and two bead sealing rings mounted eccentrically onto the strut by a fixed lower adapter plate. The strut is also comprised with a rotatable upper adapter plate that allows the air spring to take the place of the previously mounted coil spring in order to allow load and ride height adjustment where beforehand the coil spring allowed none.
