1V6023SA Mercedes-Benz Air Spring Without Piston A9423280001 | 4390N1

The 1V6023SA is the piston-free 0A4390-1 configuration listed for the Mercedes-Benz reference A9423280001. Catalogue cross references include ContiTech 4390N1 and Airtech 34390-01P. This is a bellows-only version, so the quotation and purchase order should make the absence of a lower piston explicit. From above, the bellows can appear close to a complete air spring, which makes the open lower view important when verifying the ordered configuration.

Use this model number when the requested part is the bellows configuration rather than a complete steel-piston assembly. Ask the workshop to confirm the existing lower connection and the intended repair procedure before ordering.

• The 1V6024 belongs to the same 0A4390-1 family but includes a piston and carries a different catalogue assembly reference.
• A 245 mm bellows diameter does not remove that difference between the two configurations.
• The 452 mm natural-height entry is an unloaded catalogue dimension and must not be used as a vehicle suspension adjustment value.

Manufacturer names and vehicle numbers are provided for replacement identification only. The listed cross references come from the YITAO V-series catalogue and must be checked against the complete mounting configuration. They do not represent a claim that this is an original-equipment branded product.

For a quotation, provide the model, required quantity, and destination port. Final price is confirmed in the quotation.
