Bilstein B4 OE-replacement front strut assembly (22-215833) for the Mercedes-Benz B-Class W245, built to restore factory ride quality and handling. It uses Bilstein's twin-tube DampMatic design, an amplitude-selective system that increases damping force during larger body movements for stability and reduces it under low excitation for ride comfort — all self-adjusting with no electronics. Supplied as a complete front strut and meets or exceeds OE specifications.
