VIGOR 1V8978SA Air Spring Bellows Without Piston for Truck and Trailer Suspension

The VIGOR 1V8978SA is an air spring bellows supplied without a lower piston. This configuration is intended for enquiries where the rubber bellows and upper connection are required separately from a complete air spring assembly. The supplied photographs show the open lower end, the metal top plate and the mounting connections from different angles. Keeping the SA suffix on purchase enquiries helps distinguish this item from another configuration in the same product family and reduces the risk of ordering an assembly with the wrong lower components.

The current YITAO catalogue identifies the bellows number as 0A881. Before confirming a replacement, compare the existing bellows marking, upper stud arrangement, air inlet position and lower seating interface with the supplied item. A similar exterior or a related catalogue reference does not establish engineering interchangeability. Customers should send photographs of the removed part, the full identification number and the intended suspension application so that the configuration can be reviewed before an order is accepted. A piston is not included in this listing.

For purchasing teams, separating the bellows specification from the complete assembly specification makes quotations easier to compare. Please state whether the existing piston will be retained and identify any associated mounting parts required for the repair. Installation height, clearance and connection details should be checked against the vehicle or suspension manufacturer's instructions. This page does not assign an unverified pressure rating, load capacity or service life to the product; application-specific requirements should be confirmed during the technical review.
