Purpose and vehicle placement

The presented hinge is designed for installation on the rear of the vehicle, on the right side, in Mercedes W177 series models. It is responsible for the proper opening and closing of the tailgate, maintaining its alignment, and safe interaction with other mounting elements. The placement on the vehicle is factory-defined as rear – right, which facilitates clear identification when selecting parts.

Color and paint matching

The element is factory-painted in the Mineral Grau Metallic – B39 shade, making it a perfect match for bodywork in this color. The metallic grey provides visual consistency with the tailgate and adjacent panels, which in many cases allows for reducing or completely eliminating the need for repainting after installation. This is a practical solution for accident repairs and replacing individual tailgate suspension components.

Technical and functional characteristics

The tailgate hinge belongs to the group of body structural elements that bear the loads associated with the weight of the tailgate and the forces acting during its opening and closing. A properly selected, original component ensures:

• stable tailgate guidance throughout the full range of motion,
• proper fitment with the body and seals,
• correct interaction with the actuators and tailgate lock,
• maintenance of factory clearances and rear body geometry.

Thanks to the use of an original design solution, compatibility with factory mounting points in the body and the tailgate itself is maintained, which facilitates installation and reduces the time required for adjustment.

Condition and use in repairs

The offered item is in used condition, making it an attractive cost-effective alternative to new parts while maintaining the manufacturer's original specifications. It is particularly useful in:

• accident repairs of the rear of the vehicle,
• replacing a damaged or bent tailgate hinge,
• restoring proper closing and guidance of the tailgate,
• body restoration while maintaining the factory paint color.

Using an original hinge allows for reducing the risk of problems with adjustment, squeaking, or uneven closing of the tailgate, which often occur with parts that do not meet factory specifications.

Brand and vehicle compatibility

The product comes from the Mercedes brand, which guarantees compatibility with the body structure and quality standards used in vehicles of this series. Designated as an element in the Tailgates and rear parts category, it clearly indicates its purpose for the rear zone of the body and cooperation with the tailgate in W177 models.
