Purpose and vehicle placement

The presented trunk side panel is designed for installation in the rear of the vehicle, on the left side. It is responsible for covering the inner wheel arch and the side wall of the cargo area, which results in:

• an organized look for the trunk interior,
• protection of structural elements against accidental impacts from transported cargo,
• reduction of noise and vibrations transmitted into the cabin.

Thanks to its dedicated shape, the panel works with factory mounting points, which facilitates its correct seating and stable hold during operation.

Technical characteristics and fitment

The trunk side panel for the W163 is manufactured as an interior structural component in accordance with the vehicle manufacturer's requirements. This means that:

• the panel geometry corresponds to the factory body dimensions,
• the placement of mounting holes is consistent with the original clips,
• the edge profile fits perfectly with adjacent upholstery elements and the trunk floor.

Such fitment minimizes the risk of incorrect installation and eliminates the need for modifications or "forced" fitting. This is particularly important for maintaining factory rigidity and preventing unwanted rattles while driving.

Condition, functionality, and service application

The item comes from the secondary market, which allows for an economical replacement of a damaged or worn panel while maintaining the original specification. In practice, it is suitable for situations where:

• the existing panel has been mechanically damaged (cracks, abrasions, missing pieces),
• it is necessary to restore the interior aesthetics after body repairs,
• a partial renovation of the cargo area is being carried out.

Using an original side panel allows you to maintain the visual consistency of the interior and preserve the factory character of the finish, which is important both for utility and for the potential resale of the vehicle.

• preservation of the original trunk interior finish line,

• the ability to restore aesthetics after operational damage.

For workshops and individual users, this means shorter installation time and a reduced risk of complaints related to component mismatch.
