Product Details
The Bilstein B8 8100 shock absorber is specified by dimension rather than by vehicle, here at 15.75 in. collapsed. It is the part you reach for when the build does not match a catalog application and you need a damper sized to the car you actually have.
The monotube design is what separates these. A single high-pressure gas chamber keeps the oil from aerating, so damping stays consistent as the unit heats up instead of fading away.
Discontinued - Final Sale
Bilstein has discontinued this part. We are selling the remaining stock and it will not be restocked once it is gone. Because of that, all sales on this item are final: it cannot be returned or exchanged.
Features
- Dual tube external bypass offers position sensitive damping with independent adjustment for rebound and compression
- Incremental flow adjuster offers finite and incremental changes in damping force for precise adjustments
- 60mm large bore hard anodized aluminum piston offers a greater range of damping control and delivers exceptional long-term durability
