Purpose and Body Fitment

The presented rear bumper has been specifically designed for the W177 series, taking into account the characteristic AMG styling. The appropriate edge profile, contours, and mounting geometry allow for correct installation on the body without the need for structural modifications. The part is prepared for the rear section of the vehicle, where it is responsible for absorbing some of the impact in minor collisions and for the stable integration of related body components.

Color and Paint Finish

The bumper is finished in Iridium Silver Metallic - 775, which facilitates matching the factory Mercedes paint in this shade. The metallic coating provides the characteristic depth and light reflections typical of this color, while also minimizing the scope of potential paintwork after installation. For many users, this means a quicker return of the car to full visual functionality after repairing the rear body section.

Technical and Construction Characteristics

As a component from the Bumpers and reinforcements group, the product has been developed for integration with the factory mounting points on the W177 body. The construction includes appropriate placement of fixings and space for integration with other components of the rear of the vehicle, such as reinforcements, covers, or aerodynamic elements. The bumper has a specified weight, which is important for vehicle balance and the correct selection of mounting components.

Used OEM Part – Practical Benefits

• certainty of fit to the W177 structure without the need for mounting modifications,
• preservation of the original AMG line in the rear of the vehicle,
• the possibility of economical body repair while maintaining OEM standards.
