Purpose and aerodynamic function

The tailgate spoiler in the Mercedes W177 model serves both a visual and aerodynamic function. Mounted in the rear zone, it improves the optical lowering of the body, emphasizes the trunk lid line, and stabilizes airflow at higher speeds. Thanks to the factory geometry, the element works with the roof edge and rear window, reducing air turbulence in the tailgate area.

Color and paint matching

The finish in Mojave Silver Metallic - 859 allows for installation in vehicles with the same paint code without the need for additional painting or with minimal corrective preparation. The metallic structure of the coating is consistent with the factory Mercedes palette, which makes it easier to maintain visual consistency of the entire body and reduces the risk of shade differences between elements.

Installation characteristics

The spoiler is designed for installation in the rear part of the vehicle, on the trunk lid, using the factory mounting points provided for this body model. The OEM construction allows for proper fitment with the lid contours, which translates into stable seating, no unwanted play, and correct operation of the lid in the full range of opening and closing.

Condition and service application

The element comes from the secondary market, which makes it a beneficial solution for post-accident repairs, body and paint service, or budget-friendly visual modernization of the vehicle. A used spoiler allows for maintaining the manufacturer's original specifications while reducing costs compared to a new part.

Benefits of using an original spoiler

• Factory geometry matched to the Mercedes W177 body.
• Consistent look with the trunk lid line and rear body section.
• Metallic paint Mojave Silver Metallic - 859 consistent with the manufacturer's palette.
• Possibility of use in post-accident repairs and visual modernizations.
• Cost reduction thanks to the use of secondary market parts.
