"Safer Driving Through Superior Control"- its been a mantra of Bilstein for quite a while. Choosing the right shock absorber setup will give you greater ride, handling and control. Having all three of these characteristics brings the greatest amount of safety to your driving- whether on the street or the track.

Bilstein's PSS9 kit- one of our best selling products- is specifically designed for Porsche applications. It is a performance suspension system with 9 damping adjustments, and is modeled after race suspensions. PSS9 features mono-tube gas shock absorbers with a wide range of compression and rebound settings ranging from comfort to competition.

Bilstein performance shock absorbers use the largest available piston diameter for greater sensitivity and precise control, patented digressive piston head design, and deflective disc valving the instantly reacts to changing road input.

Having complete control over your performance vehicle means increased safety for you and those around you. TRG firmly believes in selling only top-quality products with innovative designs that increase control, and in turn safety, without sacrificing performance.

Most conventional shocks are made with shock bodies cut from a piece of steel tubing, stamped internal parts and compromised tolerances. In contrast, Bilstein's shock bodies are precision formed through a unique seamless extrusion process. This provides superior strength along with high finish tolerances that are usually associated with surgical instruments. The shock body is then treated with a special paint finish durable enough to withstand grueling 240-hour salt spray tests. The finished body is mated with a solid, induction hardened steel chrome plated and polished shaft, machined valving components and highest quality seals. Combined with extreme attention to detail, Bilstein manufactures the closest thing to a hand built shock available today.
