Purpose and fitment

The presented glass was designed specifically for the Land Rover Discovery 4 L319 model and is installed in the rear part of the body on the right side. The fixed construction of the quarter glass reduces stress on the bodywork while ensuring stable seating in the door frame or side panel, which translates into airtightness and acoustic comfort in the cabin.

Its original Land Rover origin ensures the maintenance of the correct bending radius, edge geometry, and glass thickness, which facilitates installation and minimizes the risk of leaks after replacing a damaged component.

Technical characteristics of the glass

The AS2 glass class marking indicates tempered glass with appropriate light transmission, compliant with requirements for side windows in passenger vehicles. This type of glass provides:

• an appropriate level of transparency and clarity of side visibility,
• a controlled breakage pattern in the event of damage,
• compliance with safety standards applicable to side windows.

Thanks to the factory edge profile, the glass works with original seals and mounting strips, which allows for maintaining proper acoustic insulation and protection against water and dirt ingress into the interior.

Condition, origin, and benefits of choosing used glass

The item comes from a used vehicle and is offered as used OEM glass. In practice, this means maintaining factory fitment parameters while reducing repair costs compared to a new component. For many Land Rover Discovery 4 users, this is a reasonable compromise between quality and service budget.

Choosing an original, used glass with this reference allows you to:

• maintain a consistent appearance of the side body section,
• preserve factory optical and safety parameters,
• reduce the cost of repairs after a collision or mechanical damage.

Practical application and installation

The fixed rear right glass in the Discovery 4 L319 is particularly important after body and paint repairs, replacement of entire rear doors, or damage resulting from vandalism. Thanks to the preservation of the original geometry, the installation proceeds in a predictable manner for an experienced service center, and the risk of problems with closing, rattling, or leaks is limited.

Before installation, it is worth verifying the compatibility of the glass with the vehicle body as well as the condition of the seals and mounting strips – in many cases, their simultaneous replacement or proper cleaning of the mounting socket further improves the durability of the entire repair.
