The Bilstein B3 air spring provides a perfect driving experience under high load, due to the constant counter-pressure in the bellows of the air spring.

Features:

  • Uncompromising comfort and driving characteristics
  • Rapid adjustment to road and driving conditions
  • Constant damping power under any load

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.

Looks good but the wall anchors is TRASH!
Size: 3-tier shelves, Size: 3-tier shelves
The product is heavy and sturdy once you get it up completely. The issue I have is with the instructions... 1. The 5/16 drill bit is recommends is WAY TO BIG. The Anchors it comes with will slip right through. The screws that is comes with are WAY TO SMALL for the weight. I recommend getting better ones from the hardware store and painting the screws black for better aesthetics. 2. The instructions say to put it together first then hang it on the wall. That is great so you can see where you want to place it and because it is actually bigger than it looks, but you will need to de-assemble it from the bottom shelf down after you mark where you want to place it, then put that part on the wall, then reassemble it from there, securing the top part to the wall last. The instructions sucked but that is what worked best for me. Another thing is when you first assembling it, you will notice that you will have to unscrew it a bit so the pipes can fast the correct way. This will make it feel flimsy, but it will tighten up when you secure it to the wall. Also, like some people said in previous reviews, some of the black paint did peel off the pipes, not to much for me but it was noticeable if you look at it hard enough.

Love the look of these
Size: 24in-Shelve
I love the look of these. Bought for towel storage over my toilet. They look really classy and I'm so happy with them. However, its important to note that the wall anchors they provide are way too big for the screws. The screws just fall into the inside of the anchor without even being screwed in. So there's no way you could secure the wall unit with the ones provided. We had to replace the anchors with some I already had. Other than that very happy with the quality and look.

Great shelf
Size: 24in-Shelve
I’m a fan! Good quality, sturdy shelf, very easy to assemble and put on the wall. I recommend having a second person to help hold the shelf while you get the first few screws in, just to keep it level. I love the larger shelf space, it gives me a lot more storage for the bathroom.
