Land Rover Discovery 4 L319 Door Glass Front Right O/S AS2 LR040916

Land Rover Discovery 4 L319 Door Glass Front Right O/S is an original component from the Car windows group, designed for installation on the offside (O/S) of the Land Rover Discovery 4 model. Thanks to its factory-standard fitment, it ensures proper seating geometry within the door, correct operation with the window regulator mechanism, and a stable seal against wind and water.

Application and body fitment

This window is designed for installation in the front right door of the Land Rover Discovery 4 L319, meaning its shape, bending radii, and thickness have been engineered specifically for this door and body frame. Proper fitment minimizes the risk of leaks, rattling when closing, and incorrect operation of the window guides.

The positioning in the front area on the right side of the vehicle is important for both safety and passenger comfort – the glass works in conjunction with the side mirror, door seals, and soundproofing elements, affecting cabin noise levels and side visibility.

Performance and construction parameters

The AS2 glass type designation indicates the use of tempered glass with appropriate optical and strength parameters, compliant with homologation requirements for side windows. This type of glass provides:

• stable clarity and image readability in various lighting conditions,
• a controlled breakage pattern in the event of damage, reducing the risk of serious injury,
• proper cooperation with factory guides and the window regulator.

By maintaining factory dimensions and geometry, the glass allows for precise positioning in the door frame, which facilitates the adjustment of the lifting mechanism and ensures even pressure against the seals.

Product characteristics and condition

The item comes from a Land Rover vehicle and is part of the original equipment, which translates into compliance with factory quality and safety standards. As a used part, it represents a cost-effective solution while maintaining proper fitment to the body and door mechanisms.

Choosing an original glass from dismantling allows you to reduce the risk of problems typical of aftermarket replacements with imprecise dimensions, such as difficulties with closing the door, excessive wind noise, or accelerated wear of the seals. It is a practical solution for post-accident repairs, replacing damaged glass, or restoring the full functionality of the passenger door.

Benefits of using original glass in Discovery 4

Using factory glass in the Land Rover Discovery 4 L319 translates into a number of measurable benefits:

• Full compatibility with the door structure – no need for modifications, drilling, or adjusting mounts.
• Proper cooperation with the existing window lifting mechanism and seals, which reduces installation time.
• Visual consistency with other windows in the vehicle, important for body repairs and maintaining aesthetics.
• A reasonable compromise between repair costs and maintaining manufacturer standards.

This solution is particularly recommended for repairs where the priority is to maintain the original vehicle specification and the correct operation of all moving parts in the door.
