Purpose and Body Fitment

The presented strip is a component from the Trunk Lid & Rear area, intended for left-side installation at the rear of the vehicle. Its placement on a Rear, Left vehicle means the rail works with the rear roof and trunk lid area, ensuring proper guidance and support for the roof rack system. The design has been developed to maintain factory gaps, body lines, and correct water drainage from the roof surface.

Technical and Functional Characteristics

The strip serves as a load-bearing and guiding element for the roof rack, while also acting as a finishing component for the rear roof section. Its precisely shaped profile allows for:

• stable seating of roof rack feet at designated mounting points,
• maintenance of correct mounting geometry along the vehicle's axis,
• preservation of the roof's stylistic continuity in the rear area,
• reduction of unwanted vibrations and noise generated by the rack's load-bearing elements.

Thanks to its factory design, the strip integrates with the original mounting points on the body, facilitating installation and minimizing the risk of leaks or stress on the car body.

Benefits of Using an Original Roof Rail Strip

Using a dedicated strip for the W164 model helps maintain the vehicle's structural and aesthetic integrity. Key advantages include:

• Precise fit with the roof edge and trunk lid, requiring no modifications.
• Compatibility with factory roof rack systems designed for this generation of bodywork.
• Preservation of the original appearance of the vehicle's rear after repair or replacement of a damaged part.
• Restoration of full transport functionality for carrying loads on the roof.

This type of component is particularly important for repairs after collisions, mechanical damage to the roof rack, or when completing missing components after accessory removal.

Component Condition and Service Application

The strip is offered in Used condition, meaning it comes from a dismantled vehicle, but its structural parameters remain preserved to allow for continued use. This type of component is a good choice for vehicle servicing where maintaining the original mounting specification while optimizing repair costs is a priority. Replacing a damaged rail with an original component allows for the restoration of correct rack mounting and the aesthetics of the rear roof section.
