2033303311 2033303411 Control Arm Front Lower Swing Arm For Mercedes Benz W203

The Lower Control Arms 2033303311 (Left) and 2033303411 (Right) are designed for the front suspension system of Mercedes-Benz C-Class W203 (2000–2007).

Installed at the lower front suspension, these arms connect the vehicle chassis to the steering knuckle, providing critical support and stability for the front wheels. Their main role is to control the vertical movement of the wheels, maintain proper alignment angles, and absorb road shocks and vibrations.

Worn or damaged lower control arms can lead to loose steering, clunking noises, poor handling, and irregular tire wear. Replacing them helps restore safe steering response and driving comfort.

For best results, it's recommended to replace both sides together and perform a wheel alignment after installation.
