Purpose and function of the gas strut

The presented gas strut is a component of the electric tailgate system, responsible for the controlled movement of the tailgate during opening and closing. It works in conjunction with the electric drive, stabilizing the position of the tailgate and reducing mechanical stress on hinges and mounts.

Thanks to its dedicated fitment for the F31 estate body style, the strut ensures:

• correct lifting and closing force characteristics,
• consistent operation with factory control electronics,
• maintenance of proper tailgate movement geometry.

Vehicle placement and fitment

The component is designed for the left side of the vehicle, which is crucial for both mounting geometry and load distribution within the tailgate system. Using the correct strut on the appropriate side guarantees:

• proper alignment with mounting points on the body and tailgate,
• even distribution of forces on both sides of the tailgate during system operation,
• stable guidance of the tailgate throughout its full range of motion.

Its original BMW origin promotes the maintenance of factory-quality fitment and compatibility with other mechanism components.

Performance characteristics and installation benefits

The used electric tailgate gas strut is a sound solution for maintenance repairs when the existing component has lost its properties or has suffered mechanical damage. Using an original component from the same group allows you to:

• restore the correct operation of the electric tailgate opening and closing,
• reduce the risk of overloading the electric drive and hinges,
• maintain trunk operation comfort at a factory level.

A used OEM component is often a technically sensible choice compared to aftermarket replacements with uncertain performance characteristics, especially in systems that interact with vehicle electronics.

Condition and service application

The product is offered as a secondary market part, intended for service use in BMW 3 Series F31 vehicles equipped with an electric tailgate. It can be used both for typical replacement of a worn-out strut and for post-accident repairs of the rear body section.

Choosing an original used component allows for maintaining the structural integrity of the tailgate system without the need for modifying mounts or interfering with factory design solutions.
