Product Details

B4 Series Air Shock and Strut by Bilstein®. 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.

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.

Great Product
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.

Blisten 5160 Toyota Tacoma Rear Shocks
CARiD delivered them pretty darn quick and they were easy to install with instructions and video link they provided. Ride really well and that extra little cylinder for dampening really helps vs normal one tube shocks. I was missing a package containing one of the top washers and rubber grommets but used one of my old sets seeing that my original shocks were also Blisten. Had not the time to contact them yet but I am sure they will make it good!

Great But No Dust Covers and Bottom Spring Seat Cushion
They perform very well but I'm not happy about not getting a new dust cover with these. I only received 1 zip tie for the brake hose mount when I needed two. I also had to reuse the old bottom spring seat pad on the new one. This would've received 5 stars from me if it wasn't for those things.

Hey! Pick these!
This was my first experience purchasing from both CARiD and this brand of shocks. But let me tell you..This entire experience was superb, the product arrive quite quickly and well packaged. -I’ve replaced the original shocks with these and there's a noticeable difference. I also have to say that I'm not a car expert but I installed it easily.

Excellent
Have owned and driven countless trucks from fords, dodges, and Chevrolet. You won't get a better ride than with this brand. Its like riding a boat on calm water.. If you want to extend the life on everything else that goes hand in hand look no further. Bilstein knows what they're doing. Just might make you rethink the captains chair or butt pillow.
