Purpose and fitment

The offered rear right door window glass has been designed specifically for the X164 body type, taking into account the characteristic side line and seal profile. Its placement in the rear passenger-side zone allows for the precise restoration of factory glazing after a collision, glass breakage, or during body and paint repairs. The original glass ensures proper fitment with the door frame, guides, and lifting mechanism, which reduces the risk of leaks, rattling, or excessive stress during the operation of the window regulator.

Performance parameters of AS3 glass

Glass with the AS3 marking belongs to the group of windows with an increased degree of tinting, which helps improve thermal and visual comfort inside the vehicle. This type of glass:

• reduces heating of the rear cabin area on sunny days,
• increases the privacy of passengers and transported luggage,
• supports a consistent, factory look of the side window line in the X164 model. By maintaining the original optical specification and glass thickness, the window works correctly with seals and mounting elements, which translates into stable operation during use.

Installation characteristics

The rear right door window glass is intended for installation in the factory location on the rear passenger side. The glass construction is adapted to standard guides and mounts, which facilitates workshop work and shortens replacement time. Using an original component allows you to avoid geometry problems that may occur with imprecise aftermarket replacements. Choosing used, original glass is a beneficial solution for post-accident repairs when you want to maintain visual consistency with the other windows and reduce costs while maintaining the factory standard of workmanship.

Benefits of using an original Mercedes window

Using an original rear right door window glass in a Mercedes X164 allows you to maintain compliance with the vehicle's factory specification. The appropriate edge profile, fit to the seals, and correct tinting characteristics affect acoustic comfort, protection against solar radiation, and the aesthetics of the side of the body. By choosing an item from the Car windows category dedicated to a specific model, you minimize the risk of installation problems and ensure the vehicle has a consistent, professional look after the repair is completed.
