Purpose and fitment

The presented rear left door is dedicated to the CLA C117 series body, maintaining the original geometry and mounting points. Its placement on the rear left side of the vehicle ensures proper alignment with the fender, rocker panel, and pillar, which translates into correct body lines and panel gaps.

The factory design of the door allows for the transfer of accessories from the previous component (windows, locks, wiring – depending on the specific car configuration), which simplifies the service process and reduces the time required for fitting.

Color and paint layer

The door is finished in Mountain Grey Metallic - 787, which corresponds to the popular grey palette used in Mercedes CLA C117 models. The metallic paint coating provides a characteristic depth of color and good compatibility with the factory clear coat, which is important for any potential spot painting or blending of adjacent elements.

For body and paint shops, this means the ability to precisely match the color and coating structure, and for the user – a visually consistent final result after repairing the side of the body.

Structural characteristics

As a component from the Doors and door panels category, the product serves as a load-bearing side panel, responsible for:

• maintaining proper lateral body rigidity,
• correct operation of hinges and locks within the rear passenger zone,
• providing the appropriate surface for seals and trim strips,
• stable mounting of the window and internal upholstery panels.

The properly selected weight of the component helps maintain the factory load distribution in the body, which is important for suspension performance and driving comfort.

Condition and benefits of use

The door is offered as a used body component, which allows for an economical vehicle repair while maintaining original construction quality. Compared to non-original replacements, factory doors for the CLA C117 ensure better fitment to the body lines and predictable behavior during hinge and lock adjustments.

Using an original rear left panel reduces the need for additional bodywork modifications, thereby shortening repair time and reducing the risk of issues with body geometry or leaks in the door area.
