Purpose and fitment for Mercedes ML W164

The offered glass is designed as a tailgate component for the Mercedes ML W164 model, with the placement specified as Rear. Thanks to its factory geometry and the appropriate glass profile, it ensures proper fitment with the tailgate frame, maintaining airtightness and correct interaction with seals and other body components.

As a part from the Car windows category, it is prepared to operate in demanding conditions – from thermal loads to stresses resulting from bodywork movement during driving.

Technical characteristics of AS3 tinted glass

The AS3 designation refers to the tinting type and glass class used in the rear zone of the vehicle. This type of glass:

• provides limited light transmission, which improves thermal comfort inside the vehicle,
• reduces glare and improves the readability of the rearview mirror after dark,
• increases the level of privacy for luggage and passengers in the rear of the car,
• is adapted for installation in the factory mounting points of the tailgate.

AS3 tinted glass is a solution often chosen for premium class vehicles, such as Mercedes, due to the favorable combination of functionality and aesthetics.

Condition, origin, and benefits of choosing a used part

The item comes from disassembly and is offered as a used rear window. This type of component allows for an economical vehicle repair after tailgate damage or glass breakage, while maintaining the manufacturer's original specifications. Choosing an original used glass is often a reasonable compromise between cost and the quality of fitment to the bodywork.

Safety, installation, and practical aspects

A properly selected tailgate window is important not only for visual reasons but also for utility. Proper fitment to the bodywork affects:

• the rigidity of the rear body section in the tailgate area,
• proper water drainage and connection tightness,
• acoustic comfort inside the vehicle,
• passive safety in the event of a rear-end collision.

During installation, it is recommended to use professional bonding materials and follow the vehicle manufacturer's procedures, which allows for maintaining the appropriate strength of the connection between the glass and the tailgate.

Selection by numbers and additional technical support

Verification of the glass compatibility with a specific version of the Mercedes ML W164 should be based on the OEM part number and interchangeable numbers, which you will find in the technical specifications section. This is the most reliable method to avoid problems with installation and body fitment.
