Piston-Free Truck Air Spring Bellows 1V6023SA - A9423280001 / 4390N1

The VIGOR / YITAO 1V6023SA is supplied as a service air spring section without a lower piston, intended for buyers who require the bellows assembly rather than a complete lower-piston unit. It carries the Mercedes-Benz reference A9423280001 and the ContiTech reference 4390N1.

The supplied photographs show the open lower end and the upper connection, making the supply scope clear. This distinction helps purchasing teams avoid comparing a piston-free quotation against an offer for a complete assembly.

The SA suffix is part of the YITAO model identity and must remain on the order and packing description. Please identify your enquiry explicitly as 1V6023SA without piston so that quotation and receiving records describe the same supply scope.

Cross-reference entries support a focused parts enquiry only. A cross-reference does not establish engineering interchange. Complete assemblies carrying different catalogue suffixes must not be added to the order simply because they belong to a similar bellows family.

• Review the required upper arrangement and lower interface against the relevant technical information before selection.
• The existing piston and associated components are not automatically approved for reuse by this listing.
• The responsible technical team must establish the correct configuration and installation requirements for the actual application.
• No operating pressure, load rating or service-life figure is inferred from the supplied photographs.
