B4 Series Rear Driver or Passenger Side Monotube Shock Absorber (24-158657) by Bilstein. Quantity: 1 per Pack. The Bilstein B4 air suspension module. The only fully functional module for all air suspension systems in uncompromising OE quality. High-quality air suspension modules in uncompromising original manufacturer quality have only been available for a few years. Unfortunately this is why in the meantime, spare parts of significantly poorer quality and often with considerably restricted functions have spread on the market.
It’s recommended to replace shock or strut in pairs (passenger and driver side at the same time).
High OEM quality standards
Proven BILSTEIN gas pressure technology
Responds to street and vehicle conditions in milliseconds for instant adaptivity
Provides excellent comfort and perfect driving characteristics
