Bilstein Suspension
Monotube gas-pressure dampers, coilover kits, and off-road shocks from the brand that has been supplying OEM suspension to BMW, Porsche, and Mercedes for over 60 years. Everything you need to understand the lineup, pick the right series, and get the most out of your Bilstein setup.
Shop Bilstein at Track Ready ProductsAbout Bilstein
Bilstein has been building monotube gas-pressure dampers since 1954, and the technology they developed in that era still defines how performance shocks are built today. The monotube design keeps the oil and gas separated inside a single tube, which means faster response, better heat dissipation, and consistent damping whether you're doing your third lap at Willow Springs or your third hour on the highway. It's why Bilstein has been an OEM supplier to BMW, Porsche, and Mercedes for decades — the same construction goes into their aftermarket products.
The lineup runs from the B4 OE Replacement for drivers who want a factory-quality upgrade all the way up to the Clubsport coilover for track-day regulars who need independent bump and rebound adjustment. Between those two ends of the range you have the B6 for performance street use at stock height, the B8 for lowered applications, the B12 complete sport kit with matched Eibach springs, the B14 height-adjustable coilover, and the B16 with single-knob damping adjustment. On the truck and off-road side, the 5100 and 6112 series handle lifted suspensions and light off-road use.
The guides on this page cover everything from picking the right series for your driving style and vehicle height to coilover setup, off-road application, and how Bilstein's monotube construction stacks up against twin-tube alternatives in real-world use. Browse Bilstein by vehicle →
