Purpose and fitment

The presented Mercedes W221 Rear Side Window Glass Left N/S has been designed specifically for the luxury class Mercedes W221 body, taking into account the characteristic side line and rear door profile. Its placement in the rear zone on the left side guarantees compatibility with the factory body layout and maintains the consistent aesthetics of the entire glazing.

Thanks to a design that complies with factory Mercedes standards, the glass works with original guides, seals, and the lifting mechanism, which minimizes the risk of tension, rattling, or leaks after installation.

Performance properties and safety

The rear side window in the AS2 standard ensures an appropriate level of light transmission and radiation protection, in accordance with the requirements for side windows in passenger vehicles. The laminated or tempered construction (according to the factory specification for this model) is designed to reduce the risk of sharp edges in the event of damage.

The properly selected thickness and profile of the glass influence:

• the stability of the lifting and lowering mechanism,
• the damping of external noise in the rear part of the cabin,
• the maintenance of proper lateral body stiffness in the rear door area.

Characteristics of the used component

As a used component, the glass comes from vehicle dismantling and retains the original manufacturer's specification. This means factory fitment to the bodywork, compliance with the model's stylistic line, and compatibility with standard mounting elements.

Choosing an original used glass allows you to maintain visual consistency with the other windows in the vehicle, while simultaneously reducing repair costs compared to purchasing a new OEM component.

Benefits of using the original rear side window

• precise fit with the door frame and seals,
• preservation of the factory body line and the appearance of the vehicle's side,
• proper cooperation with the factory window lifting mechanism,
• maintenance of acoustic comfort in the rear part of the cabin.

For users who value the manufacturer's original solutions, this is a technically sound choice that allows for restoring the full functionality of the side zone without compromising on fitment.
