Purpose and fitment

The presented window glass has been designed specifically for the Land Rover Discovery 4 L319 model as a component mounted on the rear right side. The appropriate edge profiling and factory glass thickness guarantee compatibility with the door frame, guides, and seals, which minimizes the risk of leaks and unwanted noise while driving.

The AS2 glass class marking indicates the use of tempered glass with controlled light transmission, meeting homologation requirements for side windows. As a result, the glass maintains the proper balance between visibility and protection against excessive interior heating.

Performance parameters and safety

AS2 tempered glass is characterized by increased resistance to mechanical stress compared to standard non-tempered glass. In the event of damage, it shatters into small, relatively blunt fragments, which limits the risk of serious injury. This is particularly important in the rear door zone, where passengers are often transported.

The original origin of the component ensures the maintenance of factory optical parameters – no image distortion, proper transparency, and consistency with the body line. Thanks to this, the glass does not negatively affect the operation of side mirrors or the driver's assessment of distance.

Characteristics of the used component

As a used part, the glass retains full structural and functional utility, while offering a more favorable cost level compared to new components. For many Land Rover Discovery 4 users, this is a sensible way to restore vehicle functionality after damage to the side glazing, without sacrificing the manufacturer's original specifications.

Choosing such a solution allows for reducing the environmental footprint through the reuse of functional components, which is important for drivers who pay attention to the ecological aspect of vehicle operation.

Installation and service application

The rear right window glass for the Discovery 4 L319 is intended for installation in factory mounting points, using standard mounting elements and seals provided by the vehicle manufacturer. A correctly selected component facilitates service work – it does not require modifications or adjustments, which shortens repair time and reduces the risk of subsequent problems with door closing or window regulator operation.

Due to the importance of glazing for body rigidity and passive safety, the use of original glass is recommended wherever compliance with technical documentation and predictable structural behavior during operation are important.
