The inner center box beam for the Citroën 11CV/15CV is a critical structural component of the car. Located centrally within the chassis, it provides essential support and stability to the vehicle. Made from high-quality steel or similar materials, this box beam helps evenly distribute forces encountered during driving, preventing deformation of the body frame. Specifically designed to fit classic Citroën models, it plays a crucial role in restoring these historic cars while maintaining their original structure and characteristics. Replacement may be necessary due to wear or corrosion over time.
