The Bilstein B14 (PSS) is a ride-height-adjustable coilover suspension kit for the Mercedes-Benz C-Class (C250/C300/C350) and E-Class (E350/E400/E550). It pairs monotube gas-pressure dampers with application-matched springs on a zinc-coated, threaded body that lowers the car approximately 30-50mm. Triple-C-Technology surface coating resists corrosion, and each kit is built in Germany and tuned under motorsport conditions.
