Steel-Piston Air Spring Assembly 1V6024 - A9423200121 / 4390NP01

The VIGOR / YITAO 1V6024 is a steel-piston air spring assembly recorded with Mercedes-Benz reference A9423200121 and ContiTech reference 4390NP01. It is offered for truck suspension replacement enquiries where the buyer requires the complete assembly configuration rather than a piston-free service section. Product photographs show the upper connection, side profile and lower piston. Confirm the required arrangement against the applicable drawing before approving an order.

For this model, the full assembly reference matters more than a shared short bellows marking. Preserve NP01 and the complete YITAO model number in the purchasing record. A piston-free 4390N1 service reference describes a different supply level and is not presented here as an equivalent complete assembly.

• Complete steel-piston air spring assembly — not a piston-free service section.
• Full assembly reference (NP01 / 1V6024) must be retained in the purchasing record.
• Check upper and lower attachment details, connection arrangement and required installation information.
• Catalogue correspondence can identify a candidate, but does not prove full dimensional agreement, performance approval or engineering interchange.
• Any unresolved configuration difference should remain visible until the relevant technical review is complete.
