Purpose and body fitment

The presented glass has been designed specifically for the Land Rover Discovery Sport L550 model and is installed in the front right door. The precise edge profiling and correct bending radius guarantee proper guidance in the tracks, sealing against the weatherstrips, and correct operation with the window regulator mechanism.

Thanks to its factory origin, the glass maintains the correct dimensional tolerances, which translates into stable seating in the door frame, the absence of unwanted vibrations, and reduced cabin noise when driving at higher speeds.

AS2 glass characteristics

The AS2 marking indicates that this is tempered glass with controlled light transmittance, intended for use as a side window. This type of glass:

• ensures adequate visibility in various lighting conditions,
• is resistant to typical operational loads, such as temperature changes or minor impacts,
• shatters into small, less sharp fragments in the event of severe damage, which reduces the risk of serious cuts.

As a result, the front passenger side door window is a safe and functional element of the vehicle's glazing system, maintaining the parameters required for side windows in passenger vehicles.

Benefits of using original Land Rover glass

Using original glass dedicated to the Discovery Sport L550 allows for maintaining the stylistic and technical consistency of the vehicle's entire glazing. The appropriate glass thickness, correct tint, and fitment to factory seals contribute to:

• acoustic comfort inside the cabin – reduction of wind noise and rattling,
• stable operation of the lifting mechanism – less load on guides and cables,
• proper water drainage from the glass surface and the door frame area.

An element from this group is particularly important for post-collision repairs, replacing damaged glass, or restoring full door functionality after a window regulator failure.

Condition, origin, and installation aspects

The offered glass is a used component, which allows for combining an attractive price with the preservation of original factory parameters. For workshops and individual users, this means the possibility of an economical repair while maintaining the proper fit to the door structure.

During installation, it is recommended to use new clips, guides, or seals if their condition is questionable, in order to fully utilize the potential for sealing and mounting stability. Properly installed glass works with factory lifting and central locking systems without causing additional stress on the mechanisms.

Choosing the right glass and professional support

To ensure that the glass is compatible with the specific equipment version of your Discovery Sport, it is worth paying attention to the manufacturer's markings, body type, and placement on the vehicle. The product has assigned OEM part numbers and interchangeable numbers, which facilitate verification of compatibility with service catalogs and parts selection systems.
