Technical specifications and fitment

The presented rear bumper is a structural component dedicated to the Mercedes SLK R171 generation model, designed for mounting on the rear of the body. As a component from the Bumpers and reinforcements group, it is responsible for maintaining the correct body lines, as well as properly distributing loads in the event of minor parking collisions.

The Obsidian Black Metallic - 197 color is a popular, standard Mercedes paint, which allows the bumper to blend well with the body styling and facilitates visual matching when replacing a damaged part. The metallic finish provides an aesthetic, deep shade of black, characteristic of versions with a more dynamic, sporty look.

Vehicle function and installation benefits

The rear bumper in the Mercedes SLK R171 performs several key structural and functional roles:

• shapes the rear part of the body, ensuring consistency of the side lines and the trunk lid,
• works with reinforcement elements, influencing force distribution during minor impacts,
• enables proper mounting of external equipment (e.g., trim strips, sensors – if present in the vehicle's specific configuration),
• protects elements located behind the bumper from direct contact with obstacles.

By using an original component, the body retains proper fitment, and the body lines remain consistent with the factory design. This is particularly important in roadster-class cars, where the aesthetics of the rear body section have a significant impact on the perception of the entire vehicle.

Obsidian Black Metallic - 197 color and paint aspects

The Obsidian Black Metallic - 197 finish helps reduce the scope of paint work required when replacing a damaged bumper, especially when the vehicle is finished in the same shade. The metallic black effectively masks minor color differences resulting from wear, which facilitates the integration of the part with the rest of the bodywork.

In the case of more demanding body and paint repairs, the bumper can serve as a solid base for repainting in the same or a different color, while maintaining the proper substrate structure and geometry of the component.

Used condition and application in repairs

The item is offered in used condition, making it an attractive solution for post-accident repairs and visual vehicle corrections, where a reasonable cost relative to the car's value is a priority. A used original bumper is often a beneficial compromise between fitment quality and the budget allocated for repairs.

This solution works particularly well in situations where a quick replacement of a damaged body part is necessary, while simultaneously aiming to maintain factory geometry and compatibility with other components of the vehicle's rear section.
