VIGOR 1V3918SA Air Spring Bellows Without Piston for Commercial Vehicle Suspension

The VIGOR 1V3918SA is an air spring bellows supplied without a lower piston. The open lower end is visible in the original photographs and distinguishes this supply form from a complete piston-equipped air spring. The SA suffix must remain in the enquiry and order description so that the required contents are clear. This product should be selected for a bellows replacement requirement only after the upper connections and the intended lower interface have been checked.

The photographs show the upper connection area, rubber body and open lower opening from different angles. A replacement decision should consider how the bellows will connect to the retained components, together with the mounting orientation and air line arrangement. An existing piston should be assessed for its condition and suitability before reuse. The appearance of the rubber body or a shared base model number does not confirm that every assembly in the family has the same supply contents or installation requirements.

When requesting a quotation, state that a bellows without piston is required and provide the full 1V3918SA model. Include the reference label from the removed part, a clear upper connection photograph and the details of the lower component that will be retained. If a complete air spring is required instead, describe that separately so the supply configuration can be reviewed. Any loose nuts or other hardware should be listed in the agreed order contents. Catalogue references for a piston-equipped version should be checked separately before being used to identify this SA item.
