Purpose and vehicle placement

The presented glass is dedicated to the rear body section on the right side of the Land Rover Discovery Sport L550 model. Its placement in the rear side pillar zone means this element is responsible for:

• completing the factory body glazing line,
• providing a stable seal for the side bodywork in the trunk and rear seat area,
• maintaining proper visibility for rear-seat passengers. Thanks to its precise fit for the specific body model, installation is predictable, maintaining factory mounting points and seals.

Technical characteristics of AS2 glass

The glass marked as AS2 belongs to the group of tempered side glazings used as standard in many SUV-class vehicles. This type of glass provides:

• adequate resistance to operational stress and temperature changes,
• a controlled breakage pattern into small fragments in the event of damage,
• light transmission compliant with requirements for rear side windows. Selecting glass with the correct AS2 rating is important both from a safety perspective and for compliance with homologation regulations for the specific vehicle model.

Benefits of using original side glass

Using original glazing in the Land Rover Discovery Sport L550 allows for maintaining the structural and visual consistency of the body. Key advantages include:

• Factory fit – the shape, curvature, and thickness of the glass are consistent with the manufacturer's design, which facilitates installation and reduces the risk of leaks.
• Optical consistency – the color and structure of the glass are matched to the other windows in the vehicle, minimizing visual differences after replacing the component.
• Structural stability – properly installed glass supports the rigidity of the side bodywork in the rear pillar area. In the event of replacement after a collision or mechanical/thermal damage, using an original element from the same construction group allows for maintaining performance parameters close to factory specifications.

Component condition and service application

The offered glass belongs to the group of used parts, making it an attractive service solution for post-accident or restoration repairs. This type of component is particularly useful when:

• it is necessary to replace damaged glazing while keeping costs reasonable,
• you want to maintain the original glass specification relative to the factory installation,
• you are repairing local damage in the rear right body section without interfering with other windows. Before installation, it is recommended to perform a standard inspection of the glass edges, mounting points, and fitment to existing seals and body trim moldings.
