  • 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 todayandrsquo;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.

Great investment, and easy to assemble.
Color: Grey
Excellent dividers for the home. I purchased this set 3 years ago and recently had to place another order because the first order proved to be a perfect accessory in my basement apartment. As previously mentioned, I am in a basement apartment, and with these dividers, I can take an open space and create compartments. After a while, you forget that that open space was once a single room. These options added a great deal to my "Fonshuay," and lifestyle. This is a great investment and it was easy to assemble.

Very nice quality and appearance
Color: Beige
They were surprisingly stout and went together well. We had to return them because when we took them to where they would be used, they were too big to work in that location. Dang. But if we needed them in the future, I wouldn't hesitate to purchase them.
