Purpose and body fitment

These doors have been designed specifically as a component for the rear right section of the Mercedes W177 body. The construction is based on factory mounting points, which allows for precise alignment with the fender, rocker panel, and pillar without the need for structural body modifications. This ensures that the body geometry is maintained, along with the proper operation of the lock, hinges, and seals.

Kosmos Black Metallic color – benefits for repairs

The doors are finished in Kosmos Black Metallic, which helps reduce the scope of paintwork required during accident repairs or restoration. For many users, this means shorter vehicle downtime and the ability to maintain a uniform, elegant body style. The metallic black effectively masks minor dirt and highlights the characteristic body lines of the Mercedes W177.

Use in professional bodywork repairs

This item from the Doors and door panels category is suitable for both accident repairs and the replacement of worn or corroded doors. The original construction facilitates:

• maintaining proper lateral body rigidity,
• correct alignment of gaps between body panels,
• maintaining compatibility with factory seals and fittings,
• efficient transfer of existing components (glass, lock, wiring harness) from the damaged door.

As a result, this product is well-suited for body and paint shops where installation repeatability and a predictable final result are essential.

Characteristics of the used component

The doors come from the secondary market, which allows for lower repair costs while maintaining the original design specifications. A used body component is particularly advantageous for repairing vehicles a few years old, where the priority is a reasonable price-to-quality ratio and compliance with factory technical solutions.

Use in tuning and visual modifications

The doors in Kosmos Black Metallic can also be used for visual projects, such as body color conversions or fleet vehicle reconstructions.
