Purpose and fitment

The presented window glass is dedicated to the rear right body zone of Mercedes W251 models, which guarantees a proper fit to the factory door opening and correct operation with the window lifting mechanism. By maintaining the original edge geometry and appropriate glass thickness, the component ensures proper sealing and stable guidance in the factory tracks.

Characteristics of AS3 tinted glass

Glass marked with the AS3 class is a solution used in body areas where stronger tinting is permitted. In practice, this means:

• reduced light transmittance, which limits the heating of the vehicle interior on sunny days,
• greater comfort for rear cabin passengers by reducing glare and visibility from the outside,
• a consistent, aesthetic appearance of the side window line of the car.

The tinted rear right window also improves the protection of items transported in the passenger space, making it harder for them to be directly exposed to sunlight.

Performance parameters and installation

As a component from the Car windows category, the rear right window for the Mercedes W251 has been designed for seamless integration with factory seals, moldings, and the lifting mechanism. This facilitates installation in workshop conditions and reduces the risk of leaks or improper door closing.

The used nature of the product means that the glass comes from disassembly, which allows for an economical replacement of a damaged component while maintaining original structural parameters. This is a practical solution for users who want to restore full functionality to the side body zone without having to resort to more expensive replacements.

Benefits of using an original rear right window

Using an original tinted window in the rear right door of a Mercedes W251 ensures:

• preservation of factory aesthetics – identical shade and tint character compared to other windows,
• proper cooperation with factory equipment – tracks, window regulator, and seals,
• thermal and visual comfort for passengers in the rear of the vehicle,
• optimal fit to the door structure, without the need for modifications.

Technical support and operation

When replacing windows in a vehicle, it is worth paying attention to the general condition of the body and elements affecting safety and driving comfort. During periods of high temperatures, the efficiency of the cooling system is particularly important, which – like the windows – affects the conditions inside the vehicle.
