Purpose and function of the component

The described moulding is a part from the Window seals and strips group, dedicated to the rear left body area. Its task is to guide the edge of the door window and limit the ingress of water, dirt, and excessive noise into the vehicle interior. A properly selected moulding contributes to:

• maintaining smooth operation of the window lifting mechanism,
• reducing vibrations and unwanted noises while driving,
• maintaining even gaps between the glass and the door frame.

Original fitment for Mercedes GL X164

The component was designed specifically for the GL X164 body, which means that the geometry, profile, and mounting points are consistent with the manufacturer's factory specifications. As a result:

• the moulding sits evenly along the edge of the glass and the door frame,
• it does not require modifications or forced fitting,
• it allows for maintaining a consistent look of the vehicle's side line.

Such fitment is particularly important in large SUVs, where the length of the doors and windows is prone to wind noise – the correct moulding helps to reduce it and maintain acoustic comfort at a stable level.

Performance characteristics and installation

The moulding is intended for installation in the rear part of the vehicle on the left side, which facilitates clear identification of the installation location. As a body component working in direct contact with the glass and external factors, it should be installed while maintaining surface cleanliness and proper seating in the guides. In practice, this means:

• checking the condition of the door edge and window mechanism before installation,
• precise seating of the moulding in the designated slots,
• verifying the smoothness of the window movement after completion of work.

Thanks to the factory design, the installation proceeds in an orderly manner, and once correctly installed, the moulding works with the other door seals to create a cohesive protective system.

Condition and service application

The offered component is in used condition, which makes it a practical solution for post-accident repairs, replacing damaged mouldings after window removal, or for gradual restoration of the side bodywork. Choosing an original moulding in this condition allows for maintaining compliance with factory specifications while optimizing service costs.
