Purpose and function of the component

The presented hinge is dedicated to the Mercedes W177 Saloon body type and is mounted on the left side of the vehicle. It is responsible for the stable operation of the trunk lid, proper load distribution, and maintaining the seal and geometry of the rear part of the body. Thanks to the OEM design, compatibility with factory mounting points and stock trunk actuators is maintained.

Color and paint matching

The component comes in Polar White - 149, which allows for a consistent match to a body in the same shade without the need for immediate repainting. In the case of post-accident repairs or replacing a single hinge, such color matching reduces workshop time and makes it easier to maintain a uniform aesthetic for the rear of the vehicle.

Condition, origin, and advantages of used OEM

The hinge comes from disassembly and is offered as a used original component, which means it retains its factory construction and operating parameters. Compared to aftermarket replacements, this ensures better fitment with the trunk lid, predictable behavior during opening and closing, and alignment with the body lines. A used OEM component is also a cost-effective solution while maintaining high manufacturing quality.

Support with selection and installation

Before purchasing, it is worth verifying the compatibility of the hinge with the specific equipment version and model year of the vehicle, as well as consulting the installation method with an experienced body and paint shop. Proper adjustment of the trunk lid after replacing the hinge helps avoid stress, uneven gaps, and closing problems, which translates into the durability of the entire rear lid assembly.
