Purpose and function in the BMW F13

The described gas strut operates within the trunk lid lifting system of the BMW 6 Series F13, responsible for the controlled lifting and support of the lid. The component is adapted for installation on both the right and left sides, which facilitates selection when replacing a single strut or the entire set. Using an original BMW solution limits the risk of improper lid balance, sagging, or excessive hinge stress.

Construction and technical characteristics

The BMW F13 Boot Lid Trunk Strut High Pressure Right Left N/O/S belongs to the Gas struts, locks, hinges, and other parts group, which means it works in conjunction with other elements of the lid opening and closing mechanism. The high-pressure construction ensures adequate support force while maintaining smooth movement throughout the full range of the lid's operation. The component has been designed for long-term use in conditions of variable temperatures and loads typical for the rear section of a coupé body.

Thanks to its factory fit to the geometry of the hinges and mounting points, the strut does not require any modifications or adaptations. The proper force characteristic is maintained throughout the entire stroke, which translates into predictable lid behavior – from the moment of unlocking until it is fully open.

Benefits of using an original gas strut

Using an original gas strut in the BMW F13 brings a number of practical benefits:

• restoration of proper, even opening and closing of the trunk lid,
• reduction of load on hinges and the lock thanks to properly selected support force,
• preservation of the factory lid operating geometry without the need for adjustment,
• consistency with other elements of the BMW body system,
• possibility of replacing a single side or both sides at once for uniform operation.

A used original component is a reasonable choice for users who want to combine factory fitment with a more favorable repair cost compared to new parts.

Installation and vehicle fitment

The BMW F13 Boot Lid Trunk Strut High Pressure Right Left N/O/S has been designed as a plug-and-play element within its model. Appropriate mounting points and the correct working length allow for the trouble-free replacement of a worn strut without interfering with the hinge or lock structure. Installation on the right or left side is carried out using factory brackets, which shortens service time and minimizes the risk of installation errors.

When replacing, it is recommended to check both sides of the lid lifting system – uniform operation of the struts on both sides improves user comfort and limits asymmetrical body loads. This is particularly important in vehicles used intensively or with frequent access to the luggage compartment.

Condition and use in repair projects

The offered gas strut is a used component, which makes it an attractive solution for budget repairs, reconstructions, or vehicle modernizations. In many cases, used original components provide a better fit than replacements with uncertain specifications, especially in sensitive body mechanisms. This is a good solution both for workshops specializing in the BMW brand and for users servicing their cars themselves.

Substantive support and selection of used parts

When planning body and lid opening system repairs, it is worth considering the general principles of selecting used components – their condition, origin, and compatibility with a specific model version. Materials describing how to safely use the secondary market and how to combine used elements with the existing vehicle configuration can be helpful. In this context, it is worth reading the guide The best used parts for tuning your car, which discusses a practical approach to choosing used parts, also in modernization projects.
