What Brand is Bilstein?

Bilstein, known as BILSTEIN in Chinese, is a brand that supplies shock absorbers and air suspension OEM products to numerous automobile manufacturers in the automotive industry. It also provides OEM replacement parts and upgrade modification parts in the aftermarket. Bilstein BILSTEIN was founded in Germany in 1873 and is a wholly-owned subsidiary of ThyssenKrupp. A high-quality shock absorber must have a high-precision piston (rod) and well-sealed oil seals, high-quality damping oil (premium damping oil is the fundamental solution to damping degradation and bubble phenomena), along with a gas chamber design filled with high-pressure gas. The damping effect of a shock absorber converts the energy of vibration impact into heat. In the aftermarket for modified shock absorbers, Bilstein also produces specialized kits for major manufacturers such as ABT, AC Schnitzer, AMG, Brabus, Gemballa, Hartge, Ruf, and Techart. Additionally, with products for DTM, various Formula races, and Rally competitions, Bilstein's leading position in the shock absorber market is evident. Bilstein's product line is divided into series such as B2, B4, B6, B8, B10, B12, B14, and B16. Except for the B2, which uses a low-cost twin-tube low-pressure gas design, and the B4, which employs a single-tube low-pressure gas design, all other products feature a single-tube high-pressure gas-oil separation design. Inside Bilstein's shock absorbers, apart from the high-pressure gas chamber, another distinctive feature is the piston structure that combines the working piston and spring washers. Through the bidirectional oil passages of the working piston and the combination of different-sized spring washers, Bilstein engineers tailor the damping strength and characteristics according to the vehicle type and usage requirements. Moreover, the piston structure integrating the working piston and spring washers ensures that the shock absorber's performance maintains the initial responsiveness (Q factor) during the early stages of piston movement and the damping force as the stroke increases, consistently delivering optimal dynamic performance.
I've been studying automotive components for twenty years, and Bilstein is practically the founding father in the shock absorber realm. They started up in Germany back in 1883, predating many car brands. Their most famous innovation is the monotube high-pressure gas technology, where they replace conventional hydraulic fluid with pressurized nitrogen inside the shock tube for razor-sharp responsiveness. At my repair shop, we see customers upgrading their suspensions daily—factory parts feel mushy, but switching to Bilstein makes speed bumps disappear with surgical precision. Nowadays, premium brands like Mercedes-Benz, BMW, and Porsche equip their high-performance factory models with Bilstein as standard, and in the tuning scene, it's practically a cult icon. If you're chasing driving dynamics, this brand is a no-brainer.
