Bilstein has been the OE shock supplier to Mercedes-Benz, BMW, Porsche, and Ferrari since 1957. German-engineered B4 OE replacements, B6 sport, B8 lift-corrected, and B14/B16 coilovers — every Bilstein damper carries motorsport-derived monotube technology.
Upgrade your vehicle's rear suspension with the Bilstein B4 OE Replacement Shock Absorber. Engineered to provide the perfect balance of comfort and precision, these rear dampers are designed to restore the original ride quality and handling characteristics of your Audi A4 or S4, meeting or exceeding strict OE standards.
Your rear shocks play a critical role in vehicle stability, tire contact, and overall ride comfort. When these components wear out, you may notice increased body roll, uneven tire wear, or a harsh, bouncy ride. Replacing your worn-out units with Bilstein B4 shocks is the most effective way to bring back the smooth, controlled performance your vehicle was designed to deliver. Bilstein is synonymous with quality, and their B4 series is the gold standard for drivers who value reliability and performance without the need for complex adjustments. Trust in the expertise of Bilstein to keep your Audi performing at its best. Get the suspension components you need for your next upgrade at GGCRACING.
