Product Details

Bilstein B8 Performance Plus dampers are engineered as an upgrade over OE shocks and struts when paired with aftermarket lowering springs. The monotube construction helps maintain damping control under demanding road conditions, while the tuned valving supports improved handling balance and a sportier stance. If you are replacing worn rear dampers on a Mercedes-Benz CLS550, E320, E350, or CLS500, Bilstein 24-120227 provides a focused suspension solution backed by Bilstein’s performance damper design.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Installation Notes and Tips

Verify rear suspension configuration before ordering, especially whether the vehicle has self-leveling suspension or sport suspension. This damper uses a stem upper mount and an eye-style lower mount with a 10.1 mm lower mount type, so matching the original mounting style is important for proper installation. For best results, replace shocks in axle pairs and inspect related rear suspension components such as springs, mounts, and bushings during service.
