Application and Function in the BMW i4 G26 Gran Coupe

The presented right tailgate damper has been designed specifically for the BMW i4 G26 Gran Coupe model, ensuring stable support and precise guidance of the rear lid. It is responsible for:

• controlling the opening and closing force of the tailgate,
• holding the tailgate in its set working position,
• reducing the loads acting on the hinges and rear lid mountings,
• increasing the convenience of accessing the luggage compartment.

Thanks to its specific fit for the body model, the correct operating geometry is maintained, which translates into predictable behavior of the tailgate throughout its full range of motion.

Construction and Mounting Fit

The BMW tailgate damper is constructed as a gas strut with appropriately selected force characteristics, tailored to the weight and kinematics of the Gran Coupe tailgate. Its placement on the right side of the vehicle ensures cooperation with the left element (if present in the specific configuration), creating a balanced support system.

The original design includes factory mounting points, which facilitates installation and allows for the preservation of the original tailgate settings. Using the correct damper on the right side minimizes the risk of the lid becoming skewed, uneven closing, or excessive stress on the hinges.

Performance Characteristics of a Used Part

As a used part, the tailgate damper is sourced from disassembly and offers an economical alternative to a new original part. It allows for the restoration of proper rear lid operation in situations where the existing element has lost its properties or has suffered mechanical damage.

Choosing an original, used damper is particularly beneficial for accident repairs or servicing where maintaining the vehicle's factory specifications while optimizing costs is important.

Benefits of Using an Original Tailgate Damper

Using a dedicated tailgate damper in the BMW i4 G26 Gran Coupe offers a number of practical benefits:

• Factory Fit – maintaining the original tailgate operating characteristics without the need for mounting modifications.
• Stable Rear Lid Operation – reducing the risk of the tailgate dropping unintentionally or opening too abruptly.
• Convenient Boot Operation – easy access to the cargo space, especially important for frequent use.
• Integration with Body Structure – proper load distribution within the hinges and tailgate mountings.
