About this product

The part is built to the following specification: Length [mm]: 246, Rubber mm, Material: 67, Supplementary Article/Info 2: 667, Supplementary Article/Info 2: 689, Supplementary Article/Info 2: 732. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 001 VA 31997 000, 1922OSVAT, 4020.039, 470 050 04 27 and 5 more.
