Purpose and Function of the Component

The presented bracket belongs to the group of body elements responsible for the stable mounting of the trunk lid in the Mercedes SLK R172. Mounted on the left side of the vehicle, it works with hinges, actuators, and the lid panel, ensuring:

• maintenance of the correct lid position relative to the fenders and bumper,
• even load distribution during opening and closing,
• reduction of play and unwanted vibrations in the rear body section.

Selecting the correct bracket is particularly important after body repairs, rear-end collisions, or when replacing the trunk lid, when it is necessary to restore the factory support points.

Compatibility and Fitment

The bracket has been specifically designed for the rear body structure of the Mercedes SLK R172, ensuring factory fitment of components. This means that:

• it fits the original mounting holes on the left side of the vehicle,
• it allows for correct alignment of gaps between the lid and adjacent panels,
• it is compatible with the factory geometry of the hinges and lifting mechanism.

This allows the component to be used both for standard replacement of a damaged bracket and for more extensive rear body repairs where restoring original structural rigidity is crucial.

Performance Characteristics and Installation

As part of the Trunk Lid and Rear group, the bracket operates in an area exposed to cyclic loads resulting from frequent opening and closing of the trunk. A correctly selected and installed component:

• reduces the risk of lid misalignment and accelerated hinge wear,
• facilitates lid position adjustment during gap setting,
• supports maintaining the sealing of the rear body section by providing stable lid guidance.

Installation by an experienced body and mechanical service is recommended, using appropriate tools and adjustment procedures, to fully utilize the component's structural potential.

Product Condition and Benefits of Choosing a Used Part

The offered bracket is a used component, allowing for economical restoration of the rear body's functionality while maintaining the original design specification. In practice, this means the ability to:

• replace a damaged or deformed bracket without altering the factory design,
• reduce repair costs while maintaining high-quality fitment,
• utilize a component originating from the original Mercedes production line.

Before installation, standard verification of the mounting surfaces and attachment points is recommended to ensure correct load transfer during operation.
