Purpose and body fitment

The presented door sill strip has been designed specifically for the X156 series and is mounted on the left side of the vehicle. The component's design replicates the factory sill geometry, which facilitates proper alignment with the doors, wheel arches, and underbody covers. As a result, the continuity of the side body line and the correct operation of door seals and locks are maintained after replacement.

Kosmos Black Metallic finish

The door sill strip is finished in Kosmos Black Metallic, allowing for an aesthetic match to the factory body paint in this shade. The metallic black effectively masks minor operational dirt and visually "closes" the lower part of the vehicle's side. The primed finish provides a solid base for further paintwork if a perfect match with the individual condition of the car's paint coating is required.

Technical characteristics and installation

As a component from the Door sill strips category, the left sill serves both protective and aesthetic functions. It protects the lower edge of the body against mechanical damage typical of daily use, while also visually organizing the vehicle's side line. Installation is performed using factory mounting points, which limits the need for additional bodywork modifications and allows for the preservation of the original structural integrity of the sill.

Condition and service application

The item is in used condition, making it a reasonable choice for post-accident repairs, corrosion corrections, or restoring the vehicle to working order after localized damage to the side of the body. This type of solution is particularly useful when the priority is a technically correct repair while maintaining cost control, all while utilizing an original part from the same model line.
