Brand, origin and condition
The arm comes from Mercedes, ensuring compliance with the vehicle manufacturer's quality standards and factory technical documentation. It's part of the rearview mirror category in our catalog, but functionally, it's part of the windshield wiper system.
The product is in used condition, which in practice means that:
- comes from the dismantling of the vehicle,
- retains full functionality in terms of operation with the wiper mechanism,
- may have traces of use that do not affect correct operation.
Benefits of using the original wiper arm
Using the original arm in a Mercedes W221 maintains the integrity of the entire wiper system. Compared to aftermarket parts, the factory-installed part provides:
- precise fit with the drive axle and body,
- stable operation of the pen without excessive vibrations,
- correct scope of glass cleaning, in accordance with the manufacturer's assumptions.
For the user, this means better visibility in difficult weather conditions and a reduced risk of uneven wear of the pen.
Selection and application in practice
When selecting a wiper arm for a Mercedes W221, it's crucial to choose the right one for the specific side of the vehicle and bodywork. This part is designed for the front, left side, which should be taken into account when planning to replace just one arm or the entire set.
The arm can be used both as a replacement for a damaged element and as a preventive replacement when modernizing the wiper system, e.g. when installing new blades with a higher performance class.
