Purpose and fitment

The molding is dedicated to the rear right section of the body in W639 series models, where it is responsible for the aesthetic finish of the sliding door and the protection of its working surface. Its original Mercedes origin ensures the preservation of factory geometry, the correct profile, and mounting points, which facilitates installation and reduces the need for additional bodywork adjustments.

The placement on the vehicle, defined as Rear - right, allows for clear identification of the component when selecting parts and planning bodywork, minimizing the risk of ordering errors.

Finish and color

The molding is finished in Obsidian Black Metallic - 197, characteristic of many Mercedes paint configurations. The metallic black ensures consistency with the factory body paint while effectively masking minor operational dirt, which is important in the area of heavily used sliding doors.

As an item from the Protective and decorative moldings category, the molding combines visual and practical functions – it shields the edge and a portion of the door surface from typical mechanical damage, such as scuffs or minor impacts during daily vehicle use.

Performance characteristics and installation

The original sliding door molding ensures proper adhesion to the body panel and stable mounting, which limits the occurrence of unwanted vibrations and noise while driving. Thanks to the factory profile, the continuity of the side body line is maintained, which is significant for both aesthetic and aerodynamic reasons regarding airflow along the side of the vehicle.

The item in used condition is a beneficial solution for users who want to restore the vehicle to its proper visual and functional state while maintaining a reasonable level of repair costs. In many cases, installation is limited to removing the old molding and installing the new one using the mounting points provided by the manufacturer.

Benefits of using the original molding

• Factory fitment for the right-side sliding door in W639 models.
• Color consistency with Obsidian Black Metallic - 197 paint.
• Protection of the door edge and surface against typical operational damage.
• Aesthetic finish of the side body section, in line with the manufacturer's standard.
• A reasonable compromise between quality and cost thanks to the use of a pre-owned part.
