BILSTEIN engineers worked closely with Mercedes-Benz to develop a top-of-the-class suspension for their top-of-the-line models and the results are the air suspension system. The Mercedes-Benz S-Class (W220/C215) has this system to thank for its famed driving comfort and is also one of the world's first series production vehicles to be equipped with active springs and dampers. Bilstein B4 OE Replacement Air modules, air bags, and gas pressure shock absorbers are designed to replace the original air suspension systems on many Mercedes-Benz and Jaguars. As Bilstein is the OE supplier for these items, you can rest assured that the quality of these products meets, and typically exceeds, the standards set forth by the vehicle's manufacturer. Each B4 Air product is designed to connect directly into the original plugs on the vehicle, ensuring modification-free installation and restoration of the original feel of the vehicle. Product Features:High OEM quality standardsProven BILSTEIN gas pressure technologyResponds to street and vehicle conditions in milliseconds for instant adaptivityProvides excellent comfort and perfect driving characteristics Gas Pressure Technology Over time, the mono-tube gas pressure technology developed by BILSTEIN has established itself as a standard in automotive construction. This technology involves keeping the oil in the absorber under pressure, which prevents it from foaming when temperatures and loads are increasing. As a result, full damping power is retained even when the system is placed under extreme stress, a feature that can be observed in the self-lowering piston.Ensures a high level of traction and more precise handlingA must-have for powerful sport suspensionsAdded safety in all dynamic driving situations BILSTEIN's mono-tube technology The original and best: The original mono-tube gas pressure shock absorbers bore the BILSTEIN name, and we're still responsible for producing the best there is. BILSTEIN's mono-tube technology is the number-one choice in motorsports and series-production sports cars: no other type gives engineers the same freedom to choose the perfect installation location or position (e.g. Upside-Down technology).Large effective surface on the working piston creates increased damping power and better handlingImproved dissipation of thermal energy outwards enables a consistently high level of absorber performanceSturdy structure for added safety in Upside-Down Technology
