Component Purpose and Function

The described floor panel is dedicated to the rear right interior of the M-Class W164 series body. Its purpose is to:

• stably cover the floor structure in the rear zone of the vehicle,
• provide a suitable surface for the factory carpet or mats,
• maintain the correct geometry of the interior trim on the rear passenger side.

Thanks to its proper shape and mounting points, the panel integrates with adjacent trim elements, facilitating correct installation and reducing the risk of unwanted gaps or rattles during driving.

Compatibility and Fitment

The panel has been designed specifically for the M-Class W164 body, meaning its geometry, bending lines, and mounting points correspond to the manufacturer's factory requirements. Precise fitment for the rear right side allows for installation without bodywork modifications or interference with the floor structure.

Its original origin from the Mercedes brand promotes technical consistency with other interior elements and facilitates part identification by OEM number and interchangeable numbers available in the specifications.

Performance Characteristics and Installation

As a floor trim element in the rear right part of the vehicle, the panel operates in an area exposed to loads from passengers and transported luggage. The construction is prepared to work with factory mountings, which:

• facilitates installation in place of the original panel,
• reduces the time needed for adjustment and calibration,
• ensures stable seating without additional modifications.

The element in used condition offers a cost-effective solution while maintaining compliance with the factory specification. For certainty of fitment, it is advisable to verify the OEM part number and reference numbers in the technical specifications tab or by the vehicle's VIN.

Why Choose an Original Floor Panel

Choosing an original floor panel for the rear right part of the M-Class W164 allows for the preservation of the interior's factory structure, which is important for both comfort and the car's subsequent resale value. Material and structural consistency with the rest of the trim reduces the risk of installation problems and facilitates later servicing.

Additionally, using a component that complies with the manufacturer's documentation helps maintain the proper rigidity of the floor in the rear cabin, which is crucial for the vehicle's daily use as a family SUV or for transporting goods in the passenger area.
