Purpose and function of the gas strut

The presented gas strut operates in the rear part of the body, on the left or right side, stabilizing the movement of the tailgate. It is responsible for:

• controlled opening and closing of the lid,
• holding the lid in the open position without the need for manual support,
• reducing the load on the hinges and lid mounts,
• limiting sudden impacts when closing.

Thanks to this, operating the trunk is more predictable, and the risk of the lid falling accidentally is significantly reduced.

Construction and fitment for BMW

The strut has been designed specifically for the tailgate construction in BMW, maintaining the correct force and stroke characteristics. Proper mounting points and operating geometry ensure:

• correct guidance of the lid throughout the entire range of motion,
• compatibility with factory hinges and locks,
• consistency with the original body mounting system.

Such a fit promotes stable system operation and reduces wear on other components of the trunk opening mechanism.

Performance characteristics and installation

The tailgate gas strut in this BMW model operates in the rear of the vehicle, on both the right and left sides, which allows it to be used in the appropriate location according to the car's configuration. In practice, this means:

• the possibility of replacing a single component on the side where the failure occurred,
• maintaining even operation of the lid after replacing a pair of struts,
• no need for body modifications during installation.

This solution facilitates servicing and allows you to restore the proper operation of the tailgate without interfering with other components.

Benefits of using an original BMW component

Choosing an original gas strut dedicated to BMW translates into a number of practical advantages:

• Stable lid operation – properly selected gas force reduces overloads and improves handling comfort.
• Better body fitment – factory mounting points minimize the risk of play and unwanted noises.
• Consistency with other system components – the strut works with the lock, hinges, and lid seals in accordance with the manufacturer's specifications.

Thanks to this, you restore the factory operation of the trunk, which is important both in daily use and in the long-term operation of the vehicle.
