Purpose and fitment for Mercedes W251

The offered window glass is designed specifically as a component for the rear right door wing in Mercedes W251 class models. The placement in the vehicle is clearly defined, which facilitates the selection of the correct component when replacing a damaged window or completing the side glazing.

By maintaining the factory geometry and edge profile, the glass works with the original seals, guides, and lifting mechanism, which promotes stable system operation and reduces the risk of leaks after installation.

Technical characteristics of the AS3 tinted glass

Glass marked with the AS3 class is a solution with an increased degree of tinting, which helps to reduce interior heating and improves visual comfort for rear-seat passengers. This type of glass:

• reduces the amount of sunlight reaching the cabin,
• promotes maintaining a more stable temperature inside the vehicle,
• provides a higher level of privacy in the rear part of the car.

At the same time, adequate transparency and image clarity are maintained, which is important from the point of view of safety and compliance with homologation requirements for side windows mounted in the rear.

Condition of the item and benefits of choosing a used part

The presented window glass is a used component, which allows you to combine the functionality of an original part with an attractive purchase price. In practice, this means the possibility of restoring the full functionality of the side glazing without the need to invest in a new sub-assembly.

Choosing a used window from dismantling is also an environmentally friendly solution – reusing functional parts reduces the amount of glass waste and fits into the idea of sustainable vehicle operation.

Application in the restoration and modernization of youngtimers

The Mercedes W251 is increasingly treated as a youngtimer, in which owners strive to maintain the original appearance and functionality. When replacing side windows, it is particularly important to match the degree of tinting and the characteristics of the glass to the other body elements to avoid visual differences between individual windows.
