Purpose and fitment

The offered glass is a component from the Car windows group, intended for installation in the rear right part of the Mercedes CLA X118 estate body. This is a factory quarter glass that works with original seals, trims, and mounts, ensuring it maintains the body line and proper fitment with the chassis. Precise fitment to the specific model reduces the risk of leaks and unwanted stress on the glass.

Characteristics of AS3 glass and tinting

The AS3 tinted glass has been designed to increase vehicle comfort. This type of glass:

• limits the heating of the vehicle interior on sunny days,
• reduces glare, improving ride comfort for rear passengers,
• supports the protection of upholstery elements against fading,
• provides a higher level of privacy in the rear part of the cabin.

Thanks to the factory tinting, there is no need to use additional films, which eliminates the risk of air bubbles, peeling, or unsightly edges.

Benefits of using an original Mercedes glass

Choosing an original quarter glass for the Mercedes CLA X118 allows you to maintain the optical consistency of the vehicle's entire glazing. Factory glass is designed with consideration for body rigidity, chassis movement, and safety requirements, which translates into stability and durability of the installation. A used component of this class is a reasonable compromise between cost and quality, especially for post-accident repairs or replacing damaged glass.

A properly selected rear right glass also helps reduce air noise and vibrations that may occur when using non-original replacements with inferior geometry. This is especially important at higher speeds, where sealing and installation precision have a direct impact on acoustic comfort.

Use in repairs and upgrades

The rear right side window for the Mercedes CLA X118 is suitable both for standard replacement of a damaged element and for refreshing the bodywork of older vehicles. A used, original component allows you to maintain compatibility with the other windows in the car, which is particularly important with tinted glazing – differences in glass shade are then minimized.

Expert support and selection of used components

When choosing a used window for a Mercedes, it is worth paying attention to model compatibility, tint type, and the specific side of the vehicle. It is good practice to use original components that were designed for a given body and meet the manufacturer's requirements regarding safety and durability.
