Application and Body Fitment

The offered tailgate is designed for installation at the rear of the Mercedes A-Class W177 generation. The part is engineered as a structural component of the rear assembly, responsible for the proper closing of the luggage compartment, sealing, and maintaining the correct body line.

Its original origin from the Mercedes brand ensures adherence to factory dimensions, mounting points, and geometry, which simplifies correct alignment with fenders, the rear bumper, and lights. This makes the tailgate suitable for both accident repairs and for replacing a corroded or mechanically damaged part.

Paint Finish and Mineral Grau Metallic - B39 Color

The tailgate features a factory finish in the shade Mineral Grau Metallic - B39, which corresponds to the popular grey palette used in modern Mercedes models. The metallic paint structure ensures uniform light reflection and aesthetic matching with other body elements in the same color code.

This finish can, in many cases, minimize the scope of painting work. With the correct vehicle color match, repairs can be carried out while maintaining visual consistency, which is particularly important for fleet vehicles and vehicles serviced to manufacturer standards.

Technical Characteristics and Installation

The tailgate belongs to the group of body elements referred to as Tailgates and Rear Lids, mounted at the rear of the vehicle. Its placement on the vehicle is designated as Rear, clearly indicating its purpose for the rear assembly.

The part is used, which in practice means it comes from vehicle dismantling and retains the original manufacturer's construction. This type of part is particularly valued in body and paint shops because it:

• provides factory mounting points for hinges and gas struts,
• facilitates achieving correct gaps between body elements,
• reduces the risk of issues with latch closing and adjustment,
• allows for maintaining the original structural rigidity of the rear of the vehicle.

Why Choose an Original Used Mercedes Tailgate?

Choosing an original tailgate from dismantling often proves to be a more advantageous solution than installing an aftermarket replacement. An original body part integrates better with the existing vehicle structure, as well as with the electrical system and accessories mounted around the rear tailgate.
