Application and Function in the BMW 6 Series E64

The trunk lid gas strut is responsible for the controlled lifting and stable holding of the lid in the open position. In the BMW 6 Series E64 model, this component works in conjunction with the lid hinges, providing:

• appropriately selected support force for the trunk lid,
• uniform opening and closing speed,
• increased user safety by reducing the risk of the lid dropping unexpectedly.

Thanks to its OEM design, the strut maintains the correct mounting geometry, which translates to stable operation of the lid mechanism and proper alignment with the body.

Construction and Technical Characteristics

The BMW trunk lid gas strut is designed as a pressurized element, where compressed gas generates the lifting force. This solution ensures:

• smooth operation throughout the full range of lid movement,
• adequate resistance to typical operational loads,
• compatibility with factory mounting points on the body and the lid.

Original sourcing from the BMW brand means adherence to the parameters specified by the vehicle manufacturer, which is important for both user ergonomics and the durability of the entire lid lifting system.

Condition, Origin, and Benefits of Installation

The offered gas strut is a used part from a dismantled vehicle and is sold as a used OEM part. In practice, this means significant savings compared to a new part while retaining the factory design and fit for the BMW 6 Series E64. Installing an original dismantled strut allows you to:

• restore proper trunk lid operation after the old part has lost its support force,
• avoid problems with ill-fitting aftermarket parts of incorrect force or length,
• maintain the technical consistency of the body system with the manufacturer's intended solutions.

For workshops and individual users, this is a cost-effective and technically safe solution, as it is based on an original part from the same model line.

Installation and Selection of the Correct Part

The selection of the correct gas strut for the BMW 6 Series E64 should be based on the OEM part number and interchangeable numbers, which are detailed in the technical specifications. This allows verification of compatibility with the specific body version and vehicle year. In practice, installation involves:

• removing the worn strut from the factory mounting points,
• installing the used OEM part in the same brackets,
• checking the smooth operation of the trunk lid after replacement.

Due to its plug-and-play design, with a correctly selected part, the replacement process is simple and does not require body modifications or additional adjustments.
