Technical characteristics and fitment

The Rear Window Mercedes ML W166 Trunk Lid Glass Window Tinted Black AS3 has been manufactured as a component dedicated to installation in the rear part of the body, which guarantees proper fitment with the tailgate frame and seals. The AS3 standard tinted glass provides increased protection against solar radiation and limits visibility into the luggage compartment, which is particularly important in SUV-type vehicles.

The black color of the glass harmonizes with the factory finish elements of the rear of the vehicle, creating an aesthetic, uniform glazed surface. Thanks to the use of original production technology, the appropriate rigidity and resistance to stress are maintained, which is significant for the vehicle's passive safety.

Body function and user comfort

The Rear Window Mercedes ML W166 Trunk Lid Glass Window Tinted Black AS3 plays an important role in the body structure – it is responsible for illuminating the luggage compartment, rear visibility, and working with sealing elements and tailgate mounts. The tinted glass improves the travel comfort of rear-seat passengers by reducing glare and interior heating, which is particularly noticeable in conditions of intense sunlight.

Choosing an original, used window allows you to maintain compliance with factory optical parameters, such as the degree of tint and transparency, which is important both for driving ergonomics and for consistency with the other windows in the vehicle.

Condition, origin, and benefits of using a used part

The offered window comes from dismantling and is classified as a used original component. Such components are eagerly chosen by users who expect factory fitment and build quality while optimizing the costs of repairing the rear part of the body.

In practice, this means the ability to restore the full functionality of the trunk lid after a collision, mechanical damage, or glass breakage, while maintaining a high level of aesthetics and consistency with the other glazed elements of the vehicle.
