Purpose and fitment

The presented rear right door is dedicated to the Mercedes W177 body and constitutes a complete side panel for the rear passenger side. Its placement on the vehicle is designed to maintain factory crease lines, mounting gaps, and compatibility with the original hinges, lock, and seals used in this model.

The component comes from a used vehicle, which allows for maintaining compliance with factory production technology and the structural parameters of the Mercedes body. This is a particularly beneficial solution for post-accident repairs, where maintaining proper side rigidity and correct operation of the door zone is crucial.

Color and paintwork aspect

The door is finished in the original Polar White color, marked with the paint code specific to the Mercedes color range. Using the factory shade makes it easier to match the existing vehicle paintwork, limiting the scope of any potential paint jobs to correction or blending of adjacent elements.

For body and paint shops, this means the possibility of shortening the vehicle preparation time and reducing material costs, while maintaining the visual consistency of the entire side plane of the body.

Structural characteristics

The rear right door for the Mercedes W177 is an integral element of the side structure, working in conjunction with the sill, B and C pillars, and door opening seals. The properly selected weight of the component helps maintain the correct vehicle balance and the proper operation of the hinges and lock over a long period of use.

The original construction ensures:

• proper adhesion to seals and bodywork,
• stable closing and opening on the factory axis,
• the ability to use standard mounting points for internal equipment.

Use in repairs and upgrades

This component from the Doors and body panels category will work well both for standard post-accident repairs and for restoring the full functionality of the side part of the body after mechanical damage. The used nature of the product allows for optimizing the repair budget while maintaining the original Mercedes structural specification.

Choosing an original door in Polar White is also beneficial for visual vehicle refreshment – especially in situations where the previous element had extensive damage, corrosion, or numerous paint repairs that lowered the aesthetics of the body.
