1999 BMW 528i Suspension Air Springs

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 standards
• Proven BILSTEIN gas pressure technology
• Responds to street and vehicle conditions in milliseconds for instant adaptivity
• Ensures a high level of traction and more precise handling
• A must-have for powerful sport suspensions
• Large effective surface on the working piston creates increased damping power and better handling
• Improved dissipation of thermal energy outwards enables a consistently high level of absorber performance
• Sturdy structure for added safety in Upside-Down Technology
