Product Details

B4 Series Rear Driver or Passenger Side Air Monotube Shock Absorber (20-109097) 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.

Notes

  • It’s recommended to replace shock or strut in pairs (passenger and driver side at the same time).

Features

  • 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

The delicate axial bellows of the air spring provide very sensitive spring behaviour with a comparably low rolling radius. This ensures optimum functionality even in confined working chambers. Due to the permanent load (contraction, extension, different pressures and temperatures), the material is worn out and may eventually leak. If the air bellows cannot be inflated any more, the vehicle is no longer fit to drive. Technical further developments from the original application to today’s part are usually easily recognizable. Due to higher efficiency and BILSTEIN’s obligation to increasingly employ environmentally friendly materials, the sheathing of the bump stop no longer contains chromium VI. Apart from that, all old parts by BILSTEIN are recycled in an environmentally friendly manner via the Partslife initiative. Due to the permanent movement and mileage, the high gas-pressure and the permanent oil contact, the seals in particular will become worn. If oil leaks, the air suspension module and other parts such as seals and valves lose their functionality.

In 1954, Bilstein® was the first to realize the potential offered by an idea of Prof. Bourcier de Carbon, a French researcher in the field of vibrations. The aim was to eliminate the physical disadvantages of the conventional telescopic shock absorbers, whilst at the same time making the dampers lighter and able to be fitted in any position. The name Bilstein has for many decades been closely associated with high tech in the field of suspension design, driving comfort and safety. In order to expand this position in the future, Bilstein became a division of ThyssenKrupp Technologies AG in 1988, and a wholly-owned subsidiary in 2005. The partnership and co-operation within the group will enable the company to continue to inspire with innovations in the traditional Bilstein way.

Great price and was delivered quickly. Be sure to order for both sides as recommended. I tried to avoid and therefore doubled my repair time.
