Intended Use and Fitment for Mercedes W164

The gas spring has been specifically designed for the Mercedes W164 body, taking into account the geometry of the hinges and the weight of the trunk lid. Its placement on the left side allows for proper cooperation with the right strut, resulting in even lifting and holding of the lid in the desired position.

Thanks to its construction, which aligns with factory solutions used in Mercedes vehicles, the part maintains its correct operating characteristics – from the initiation of opening to the full lift of the lid. This is particularly important in vehicles equipped with heavier rear body finishes.

Strut Construction and Operating Characteristics

The trunk gas spring utilizes gas pressure to generate lifting force, enabling smooth and controlled opening of the lid. The appropriately selected force characteristic:

• stabilizes the lid's movement throughout its entire operating range,
• reduces the risk of sudden dropping when partially open,
• ensures comfortable operation even with frequent trunk use.

Precise fitment to the W164 body structure ensures the strut works with the hinges without excessive stress, contributing to a longer lifespan of the entire rear lid system.

Application in the Tailgate and Rear Category

This part belongs to the Tailgate and Rear group, responsible for the safe and convenient use of the rear of the vehicle. Replacing a worn gas spring with a functional left-side strut:

• improves the lid's hold in the open position,
• reduces stress on the hinges and lock,
• minimizes the risk of uncontrolled lid descent.

This is a practical solution for both post-accident repairs and standard vehicle maintenance when factory parts have lost their original parameters.

Condition and Benefits of Using a Used Part

The trunk strut is offered as a used part, allowing for economical repair while maintaining the original mounting specifications. Choosing this option is beneficial when you prioritize:

• maintaining the factory method of mounting and guiding the lid,
• reducing service costs while ensuring proper functionality,
• consistency with other components of the rear lid system.

A correctly selected left-side strut restores the proper operation of the entire trunk opening and closing mechanism, directly impacting the comfort of using the car.
