OE Ride Quality • Rear Suspension Refresh

Bilstein B4 OE Replacement Rear Shock Absorber — Mercedes-Benz C-Class & CLK (2001–2009)

Fix bouncy ride, restore stability, and bring back factory comfort with Bilstein’s OE-spec B4 rear dampers — direct-fit for many W203 C-Class and W209 CLK models.

If your Mercedes feels bouncy, loose, or unstable over bumps, worn rear shocks are usually the culprit. The Bilstein B4 is engineered to meet or exceed original equipment standards, making it the ideal choice for owners who want to restore factory ride quality without going to a stiff sport damper.

Perfect for daily-driven cars, long highway trips, and refreshed suspension builds — especially when paired with fresh rear mounts and proper alignment.

Signs Your Rear Shocks Are Worn

• Rear end feels bouncy or “floating” after bumps
• Reduced stability during braking or lane changes
• Clunking/squeaking noises from the rear over rough roads
• Fluid leaking from the shock body
• Uneven tire wear or poor ride comfort
