Purpose and fitment

The presented window glass has been designed specifically for the rear left body section of the premium SUV, the Mercedes GL X164 generation. As a rear quarter side window, it is responsible for illuminating the passenger and luggage compartment while simultaneously contributing to the side profile of the body, which is why its proper fitment is important for both aesthetic and functional reasons.

The original OEM design facilitates installation in place of the factory component without the need for bodywork or seal modifications. This ensures stylistic consistency and proper adhesion of the glass to the body frame, which affects sealing and reduces cabin noise.

Characteristics of AS2 glass and blue tint

Glass marked with the AS2 class meets rigorous requirements regarding light transmission and safety, typical for side windows in passenger vehicles. The blue tint improves driving comfort on sunny days by reducing glare and partially limiting interior heating, which is particularly noticeable in large SUVs.

The use of tinted glass results in a more visually cohesive appearance of the side body, especially when combined with other factory-tinted windows. It is a practical and aesthetic solution that helps maintain the characteristic, elegant look of the Mercedes GL X164.

Condition of the component and benefits of choosing used parts

The offered window glass comes from the used parts segment, which allows for a significant reduction in repair costs compared to a new component, while maintaining the manufacturer's original specifications. For many owners of premium cars, this is an optimal compromise between quality and budget, especially for post-accident repairs or the restoration of older models.

Choosing an original glass from dismantling reduces the risk of fitment issues typical of cheaper replacements. Compliance with factory glass parameters is maintained, which is important for safety, acoustic comfort, and the vehicle's appearance.

Why choose original Mercedes Car windows

Using original windows in a Mercedes translates into stable performance characteristics and predictable body behavior in the long term. Factory glass is designed with consideration for body rigidity, seal performance, and aerodynamics, which is why its re-installation helps maintain the original design assumptions.

Used originals and current service trends
