Product Details
The Bilstein B8 5165 shock absorber is specified by dimension rather than by vehicle, here at 12.30 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.
Inside is Bilstein's monotube design, gas and oil separated by a floating piston. That is what keeps the damping honest when the surface turns rough and the temperature climbs.
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. If you want the current-production part instead, Bilstein replaced this one with part 25-331745.
Features
- 46mm monotube design ensures consistent, fade-free performance in all conditions
