Purpose and function of the hood gas strut

The BMW 5 F10 F11 Gas Pressure Pressurized Bonnet Spring Engine Hood Active is responsible for smooth opening and holding the hood in a stable position during service work or fluid checks. Thanks to its precisely calibrated gas pressure characteristics, this component works in tandem with the hood hinges, relieving the user and reducing the stress on the body structure.

A properly selected gas strut results in:

• more predictable hood behavior during opening and closing,
• reduction of vibrations and jerks at the end of the movement phase,
• increased safety when working in the engine bay.

Original origin and replacement numbers

The presented item comes from the BMW group, which ensures compliance with factory manufacturing and fitment standards. The gas strut has a dedicated OEM part number and assigned replacement numbers, which facilitates verification of compatibility with a specific vehicle configuration and production year. This allows for precise matching of the component to the existing hood mounting system, without the need for modifications or adaptations.

If you want to better understand why original used components are often a more favorable choice than aftermarket replacements, it is worth reading the practical tips in the article 5 reasons why a used OEM part is a better choice than a replacement.

Condition of the item and installation aspects

The gas strut is offered as a used part, which in practice means it retains its factory geometry, mounting points, and operating characteristics consistent with the original design. This type of component, after proper verification, allows for the restoration of the correct operation of the hood lifting mechanism without interfering with the body structure.

In a typical installation scenario, replacing the gas strut comes down to:

• removing the worn component from the mounts on the body and hood,
• seating the used gas strut in the existing mounting points,
• checking the smoothness of the hood movement across the full range of opening.

This approach helps minimize vehicle downtime and maintain consistency with the factory hood support system.

Application within the bodywork and Trunk lids and rear parts group

Although the product belongs to the Trunk lids and rear parts group, its function in this case concerns the front engine hood. Structurally, it is a component similar to the gas struts used for trunk lids – it uses a similar operating principle based on compressed gas and telescopic guidance. Thanks to this solution, a repeatable, controlled movement is achieved, along with a reduction in the loads transferred to the hinges and body panels.

If you are planning a comprehensive repair or upgrade of the bodywork area related to lifting covers in your BMW and need other elements from the same group, such as additional gas struts, brackets, or mounting hardware, check the available parts in the BMW Trunk lids and rear parts category.

Benefits of using an original hood gas strut

Using an original hood gas strut in a BMW F10/F11 translates into a number of practical benefits in daily use:

• preservation of the factory opening and closing characteristics of the hood,
• secure support of the hood during service work,
• reduction of the risk of damage resulting from the hood falling suddenly,
• consistency with other bodywork system components.

For users who expect predictable performance and compliance with the manufacturer’s design, choosing such a component is a reasonable, technically justified solution.
