Purpose and technical function

The presented rear bumper has been designed specifically for the W177 series body, taking into account factory mounting points and body lines. Its placement in the rear of the vehicle means that the component works with the body's load-bearing structure, passive safety systems, and rear lighting, ensuring proper force distribution in the event of low and medium-energy collisions.

As a part from the Bumpers and reinforcements group, the component performs several key functions:

• protection of the rear body zone against mechanical damage during minor impacts,
• stable mounting of trim elements and lighting,
• maintaining proper aerodynamics of the rear part of the vehicle,
• preserving the factory geometry of the body lines.

Visual characteristics and Jupiter Red - 589 color

The finish in the Jupiter Red - 589 shade is characteristic of sporty Mercedes body configurations, which allows for consistent matching with other body panels in the same paint code. As a result, the bumper can be used both for post-accident repairs and for visually refreshing the vehicle, minimizing the need for full painting of the entire element.

The sporty character of the rear bumper helps maintain the dynamic body line, and the appropriately selected mass of the component supports correct load distribution in the rear of the car. For the user, this means maintaining the factory look and predictable vehicle behavior while driving.

Condition, fitment, and assembly aspects

The element is in used condition, which in practice means it comes from disassembly and may show signs of wear typical for this class of parts, while maintaining structural functionality. For workshops and individual users, this is a solution that allows for an economical yet technically correct repair of the rear body zone.

The bumper has been developed as a component dedicated to a specific platform, which facilitates installation at factory mounting points. Proper fitment to the body lines limits the need for additional modifications, and the use of an original Mercedes part promotes consistency with other body elements.

Benefits of using an original rear bumper

Using an original rear bumper in Jupiter Red - 589 translates into several practical benefits:

• preservation of the factory look and character of the sporty body version,
• compatibility with the load-bearing structure and reinforcing elements in the rear of the vehicle,
• possibility of using existing mounting points and fasteners,
• reduction in the scope of body and paint work during repair.

For users who value visual and technical consistency of the vehicle, choosing an original component from the bumpers and reinforcements group is a solution that ensures a predictable final result and easier integration with other body elements.
