VIGOR 1V6173 Truck Air Spring Assembly with Plastic Piston 6173 NP40 Reference

The VIGOR 1V6173 is a commercial vehicle air spring assembly supplied with an upper plate, rubber bellows and a plastic piston. Product photographs show the air connection, side profile and lower piston, while the dimension drawing provides a practical starting point for checking the assembly against the unit being replaced.

For configuration verification before ordering, send a clear image of the old part together with its complete part number and our team will review the details.

The YITAO catalogue lists ContiTech 6173 NP40 and 6173 NP42, together with Mercedes references A 961 320 54 21, A 961 320 46 21 and A 961 320 42 21, for the 1V6173 catalogue entry.

These are catalogue search references only. The specific vehicle application, mounting arrangement and configuration must be confirmed. A shared reference alone does not establish engineering interchangeability — please compare the top connection, piston and dimensions with the original assembly before ordering.

The supplied drawing identifies a 262 mm upper plate and a 200 mm piston diameter, and also shows the air connection position and mounting details. Different versions may use different bellows markings or accessories, so keep the complete part number with your enquiry.

The drawing is intended to support product identification; stated dimensions and operating positions should be checked against your particular application rather than used as a substitute for installation verification.

When requesting a quotation, please provide the required quantity, destination port, original part number and any branding requirements. The indicative FOB price is USD 35 per piece, subject to confirmation of the order and configuration.

• Products are packed in export cartons.
• The stated annual capacity is a company-wide figure.
• Our team can review the available details with you and confirm the appropriate supply arrangement before an order is placed.
