Bilstein has been building monotube gas-pressure shocks since 1954, starting in Ennepetal, Germany. They hold the patent on the inverted monotube damper design that became the gold standard for OEM and aftermarket suspension. BMW, Porsche, Mercedes, Ford, and GM all run Bilstein dampers from the factory on performance trims. That tells you something about the engineering.
The lineup breaks down by color. Yellow B6 shocks are their heavy-duty monotube replacement for stock suspension. Pair them with lowering springs and you get a damper that actually matches the shorter travel. B8 shocks (also yellow) are valved specifically for lowered cars, so the rebound and compression rates make sense at a lower ride height instead of bottoming out on every expansion joint.
B12 Pro-Kit and B14 PSS kits bundle Bilstein dampers with Eibach springs. The B12 gives you a mild drop (around 30mm on most platforms) with matched valving. The B14 adds threaded ride-height adjustment so you can dial the drop to your preference without cutting springs like it's 2004.
B16 PSS10 is their full coilover. Ten-stage adjustable damping, threaded body for height adjustment, and the same monotube construction running through the whole range. It sits between a budget coilover and a full race setup, which makes it a solid option for street cars that see occasional track days.
MartiniWorks carries Bilstein shocks, struts, and coilover kits across their product lines. If you want dampers that perform without needing a rebuild every season, Bilstein has been the answer for seven decades.
