VIGOR 1V3918 Truck Air Spring with Iron Piston - A9423201321 Catalogue Reference

The VIGOR 1V3918 is a commercial vehicle air spring assembly fitted with an iron piston, intended for suspension replacement and repair enquiries. The supplied photographs show the black upper assembly, flexible bellows and lower piston from four angles, allowing buyers to compare the actual configuration before ordering.

The YITAO catalogue identifies the bellows as 0V3918. Please specify the complete model 1V3918 when requesting a quotation, since an assembly supplied with a piston must be distinguished from a bellows-only version.

For customers identifying a replacement by an existing number, the catalogue records the following Mercedes-Benz references: A9423201321, A9423282321, A9423202217 and A9423202221. It also lists Contitech 4183NP23, Airtech 34183-23K, 34187-01 C and 34183-23 C, Airfren 20.4183.23M, DT 4.80483 and Granning 93918.

These are catalogue identification references. They help start a technical comparison, but do not by themselves establish dimensional equivalence, vehicle fitment or approved interchangeability for every installation.

The iron piston is an important feature when comparing this assembly with alternatives. Buyers should check the upper locating features, air connection, lower mounting arrangement and available installation space against the existing part. A clear photograph of the original label and both mounting faces helps distinguish similar-looking variants.

Thread specifications, operating height and the required vehicle application should be confirmed with YITAO before a purchase order is released. The photographs are intended to show appearance rather than provide a dimensioned installation guide.
