Purpose and Body Fitment

This glass is specifically designed for the rear right area of Mercedes ML W166 generation models. Its fixed nature means it lacks a lowering mechanism, contributing to a stable side structure, good body rigidity, and reduced potential sources of noise and vibration.

Precise fitment to the body lines facilitates installation in factory mounting points, without the need for modifications to the door frame or seals. This solution is particularly beneficial for professional post-accident repairs and for replacing damaged glass with a component that matches the original specification.

AS3 Tinted Glass Characteristics

The AS3 designation refers to a type of automotive glass suitable for use in the rear of a vehicle. The tinted surface helps to reduce solar radiation penetration, which:

• minimizes interior cabin heating on sunny days,
• improves comfort for rear seat passengers,
• enhances interior privacy,
• reduces glare affecting mirror visibility.

As a result, this glass performs well in both daily use and for vehicles used on longer journeys, where stable thermal and optical conditions are important.

Installation Parameters and Service Application

The designation as rear right side clearly identifies the installation position and minimizes the risk of errors when selecting parts. This is particularly important for complex body geometries, such as premium SUVs.

The glass is suitable for service applications in vehicles after collisions, for replacing components after mechanical damage, or cracks resulting from wear and tear. Maintaining the factory type of glass and tint level helps preserve the visual consistency of the entire side glazing area.

Condition and Benefits of Choosing Used Parts

This item comes from the used automotive glass category, allowing for a reduced repair cost while maintaining the original structural specification. In practice, this means:

• the possibility of economically repairing a higher-class vehicle,
• preserving the factory character of the glazing,
• reducing waste through the reuse of functional components.

For body shops and independent service centers, choosing this type of glass is a way to combine a technologically sound repair with an attractive budget for the end customer.
