Purpose and body fitment

The presented quarter window has been designed specifically for the rear left section of the W168 series model, which guarantees proper fitment to the window frame and seals. The precise profiling of the edges allows for correct seating in the factory mounting points without the need for body modifications.

Its placement in the rear axle zone contributes to proper interior illumination and maintains the vehicle's consistent side profile. Using a window with the correct AS2 specification allows for maintaining the appropriate level of light transmission and user comfort.

Technical characteristics of the quarter window

As an element from the Car windows group, the rear left quarter window is responsible for the tightness of the side body section and the stability of the glazed area. The AS2 construction type indicates a window intended for installation in areas other than the windshield, with appropriately selected optical and strength parameters.

The fixed nature of the element (non-opening window) helps maintain the lateral rigidity of the body, and the properly selected thickness and type of glass limit the penetration of outside noise. As a result, replacing a damaged quarter window with a part of the matching specification allows for the restoration of the vehicle's original performance characteristics.

Benefits of using an original Mercedes window

Using an original window dedicated to the W168 series ensures:

• precise fitment with the door frame or side panel,
• proper cooperation with factory seals and trim strips,
• preservation of the original glazing geometry, which is important for body alignment control,
• consistent appearance of the side window line with other body elements.

A used original element is a cost-effective solution that simultaneously allows for maintaining the manufacturing standard in accordance with the manufacturer's specifications. In the case of post-accident repairs or replacing a damaged side window, this is important for both aesthetics and body tightness.

Safety, AS2 standard, and OEM quality

The AS2 marking refers to the class of glass used in the side and rear parts of the body, where appropriate mechanical resistance and controlled light transmission are required. Using a window with this specification helps maintain proper visibility conditions and driving comfort, while meeting the homologation requirements for this vehicle zone.
