Purpose and function of the gas strut

The presented gas strut is responsible for the controlled lifting and support of the trunk lid in the BMW F44 model. Thanks to the use of gas pressure, this component stabilizes the movement of the lid, limits its sagging, and improves the comfort of daily trunk operation. Its placement in the rear tailgate area makes it a component that directly affects the ergonomics of vehicle use. A properly selected strut minimizes the load on hinges and mounts, and also reduces the risk of the lid suddenly falling, which is important for both user safety and the protection of transported cargo.

Construction and performance parameters

The trunk lid strut uses gas technology, where compressed gas is responsible for generating lifting force. This design ensures:

• smooth opening and closing of the lid without jerking,
• stable holding of the lid in the upper position,
• performance characteristics properly matched to the weight of the lid in the BMW F44. The element has been designed as part of the original body system, which translates into the correct fit of length, stroke, and operating force to the specific design of the rear part of the vehicle. A used OEM component retains the factory mounting geometry, which facilitates installation and reduces the risk of improper fitment.

Compatibility and installation

The strut is intended for installation in the rear body zone, within the trunk lid area. The design based on factory mounting points allows for the direct replacement of a worn element without the need for modifications. In practice, this means:

• maintaining the original opening geometry of the lid,
• no need for additional adapters,
• shorter time required for replacement compared to universal solutions. To maintain even operation of the trunk lid, it is recommended to check both struts working in pairs and replace them in the event of a noticeable decrease in the efficiency of lifting or holding the lid.

Benefits of using an original BMW strut

Using an original, used strut in the BMW F44 allows for maintaining the structural integrity of the rear body. Key advantages include:

• factory fit for the model – compliance with the vehicle manufacturer's design,
• stable trunk lid operating characteristics,
• reduction of the risk of damage to hinges and mounts thanks to the correct lifting force,
• more predictable behavior of the lid compared to replacements with uncertain parameters. For the user, this means more convenient trunk operation, less load on structural elements, and maintaining functionality in accordance with the manufacturer's assumptions.
