Intended Use and Function of the Part

The presented sunroof seal trim is dedicated to Range Rover L405 models and is installed on the left side of the vehicle. It is responsible for properly sealing the sunroof perimeter and providing an aesthetic finish to the edges, which is important for both acoustic comfort and protection against moisture.

Thanks to its precise profile and fit to the factory roof covering, this part helps maintain stable sunroof operation and reduces the risk of leaks in the critical area where the glass meets the body.

Construction and Fit for Range Rover L405

The trim belongs to the Protective and Decorative Trims group, meaning it serves both sealing and finishing functions. Its shape and geometry are adapted to the factory sunroof of the Range Rover L405, allowing for installation without altering the roof structure.

Its placement on the left side facilitates unambiguous part identification for technicians and users during replacement. Proper alignment with original mounting points reduces material stress and contributes to maintaining a seal over the long term.

Condition, Installation, and Service Application

This part is a used original part obtained from disassembly and is offered as a used original part, which helps maintain consistency with the factory body finish standard. This type of component is particularly useful for rectifying sunroof leaks, replacing damaged trims after a collision, or during comprehensive renovation of the upper body section.

In workshop practice, the trim can be installed as a replacement for a worn or deformed part, restoring proper seal adhesion and reducing the risk of water leaks into the headliner and pillars.

Benefits of Using an Original Sunroof Trim

• Factory Fit – geometry consistent with the Range Rover L405 sunroof construction, requiring no modifications.
• Stable sealing of the sunroof perimeter, contributing to interior protection against moisture.
• Aesthetic finish of the roof edge, consistent with other body elements.
