Bilstein B4 OE Replacement (Air) dampers are designed to replace the original air suspension systems on many European brand vehicles. Bilstein is an OE supplier for air suspension systems; the quality of these products meets, and typically exceeds, the standards set forth by the vehicle's manufacturer. Bilstein B4 OE Replacement (Air) dampers are designed to connect directly into the original connectors on the vehicle, ensuring modification-free installation and restoration of the original feel of the vehicle.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).
  • Position: Front

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.

The cutest earrings I've seen in a while.
Color: 07.Jul, Color: 07.Jul
We were so happy to get these beautiful and cute silver stud butterfly earrings. The colored CZ let us customize the color to personal preference, which let us pick the perfect option. I really like the silver setting. It is quite well done, and looks far more premium and higher quality than the low price would lead you to believe. One thing I really like about these earrings is the size. These ended up being the perfect size, and made for a very cute look. I honestly think these might become the new daily-wear earrings. They look fantastic. Included are the earrings, a pouch, and two styles of backing. Both backing options were very easy to use, and held the earrings securely. The stud was of good quality, and plated in silver along the whole stud. It is difficult to tell for sure, but this seems like the plating was well done. I think these should hold up well over time. The studs are a little on the long side, but no discomfort was had wearing them. Honestly, I thought it made it easier to put them on. Though, they might not be a good one to wear sleeping or something. It is easy to recommend these super cute earrings. They will be worn frequently, come in a variety of colors, and are well made. I am very happy with them.

These are very pretty. The perfect size for any age ear. Really girly. They don't hurt the ears and they are not too heavy. Nice and light.

These little butterfly Earrings are the perfect touch of personality for your ears. I got these for a friend's birthday and she's worn them every day since. When I picked these up, they were advertised as sterling silver which was a necessity for her ears. She hasnt had any issues and she hasn't had to take them out at all. The clasps are your average butterfly backing. And she did note that the back came off during sleep one night but it could be she is a hard sleeper. Other than that, they are secure. They are larger studs. Not awful large or gaudy. But people have noticed and complimented on them. They add that perfect touch of whimsy without exclaiming give me attention. Perfect to dress up or down and birthstones match anything after all!

Cute little butterflies!
Color: 10.Oct(Pink Tourmaline), Color: 10.Oct(Pink Tourmaline)
I got these for my daughter who just recently got her ears pierced for the first time. Since she is so young, I decided to try them first to see how well they handle. First, I was very impressed that they included plastic and metal backs. There’s also a nice little baggie to put the earrings in when they’re not in use. Second, my ears are very sensitive, which was a concern with wearing these, but after a few hours, they seemed to be fine still. Usually, after a few hours, I have to take earrings out. I could have worn these for longer and been OK. Last they are super cute! They match the description and color perfectly! I was very impressed. I could definitely see myself buying another pair. The earrings were also very good size not too big and not too small. Perfect for adult or child.

Beautiful very colorful and comfortable
Color: 02.Feb(Amethyst)
These really are so cute--the purple color of the butterfly really stands out and when I'm wearing them, I can't even tell that I have them on.
