Purpose and vehicle placement

The presented strut operates in the rear part of the body, on the right side, responsible for supporting and guiding the trunk lid in W166 series models. Its placement in the rear zone means this component has a direct impact on the convenience of accessing the cargo space and the safety of using the tailgate during loading and unloading.

Thanks to its precise fit to the Mercedes body structure, the strut works in tandem with the tailgate hinges and mounts, reducing unwanted play and ensuring predictable movement of the trunk lid throughout its full range of motion.

Technical and functional characteristics

The trunk lid strut in this configuration is designed as a component operating along the axis of the lid's movement, transferring loads resulting from the weight of the lid and the forces acting during opening and closing. The design is adapted to the geometry of the W166 body, which allows for:

• stable holding of the lid in the open position,
• controlled guidance during closing,
• reduction of stress acting on hinges and mounts.

Its original Mercedes origin helps maintain consistency with the factory mechanical and electronic solutions used in the rear of the vehicle, which is essential when servicing the trunk lid system.

Component condition and service application

The strut is offered in used condition, which allows for an economical replacement of a damaged or worn part while maintaining compliance with factory specifications. This type of part is suitable both for standard repairs after operational wear and for restoring full functionality of the tailgate after mechanical damage in the rear body zone.

Using an original strut instead of a faulty component helps reduce the risk of improper lid operation, such as sagging, uneven lifting, or excessive strain on the hinges, which in the long run affects the durability of the entire system.

Benefits of using an original strut

Choosing this trunk lid strut model for the Mercedes W166 allows for maintaining the structural integrity of the vehicle's rear section. The most important advantages include:

• factory fit to the geometry of the lid and body,
• predictable operating characteristics during opening and closing,
• reduction of loads acting on hinges and mounts,
• suitability for professional service repairs.

As a result, the strut is a practical solution for users and workshops that want to restore the proper operation of the tailgate without interfering with the vehicle's construction.
