Purpose and function of the rear bumper

The presented rear bumper is designed as a protective and structural element of the rear body zone in W166 series models. It is responsible for absorbing part of the energy during minor collisions, protecting structural components, and maintaining the correct geometry of the body lines. Thanks to factory fitting for the specific body generation, the installation process is straightforward, utilizing the original mounting points.

Diamond White Metallic - 799 color and visual aspect

The factory paint in Diamond White Metallic - 799 is a distinctive, pearlescent shade of white used in vehicles of this brand. Using a bumper in this color reduces the need for full repainting, which is particularly beneficial for repairs where other body panels retain their original coating. The metallic structure of the paint ensures consistency with the remaining body panels, which translates into an aesthetic final result after installation.

Vehicle placement and structural fitment

The component is intended for installation at the rear of the vehicle, in the area of the outer body cover. The bumper construction is prepared to work with factory reinforcements, brackets, and other components of the rear body zone, which facilitates proper alignment of the edges with the fenders, trunk lid, and trim strips. Such fitment promotes the maintenance of proper aerodynamics and reduces the risk of unwanted gaps or stresses in the bodywork.

Characteristics of the used part

The bumper comes from an operated vehicle, which means it is a used part. This type of component is a good solution for post-accident repairs when the priority is to maintain original geometry and compatibility with factory mounting points. Choosing a used OEM element often allows for cost reduction compared to new replacements, while maintaining proper fitment for the specific model.

Application in post-accident repairs and upgrades

This rear bumper will work well both for standard replacement of a damaged part after a collision and for upgrade projects aimed at restoring a consistent body appearance. It can be used in body and paint workshops, brand-specialized service centers, and by individual users performing repairs on their own. In the case of extensive body repairs, it is worth considering other elements in the same zone, such as reinforcements, mounts, or covers, to ensure full functionality of the rear part of the vehicle.
