This month our featured brand is Bilstein Shocks.
Bilstein was the first company to apply the patented gas pressure principle to control ride characteristics on vehicles and introduced the world’s first ever monotube gas pressure shock absorber. In 2018, Bilstein is still known as the leader in monotube gas pressure shock absorber technology. There is no other shock manufacturer that has been able to equal the performance and enhanced ride characteristics of Bilstein. The Bilstein name is known not only for monotube gas pressure shock absorbers, but also for single and twin tube Macpherson strut style suspensions.
Ride, control and handing is what a shock absorber provides you. Compromise in one area would create a problem in another. Bilstein’s patented design decreases the need for that compromise. The rising rate valving of the Bilstein shock absorber allows the necessary damping to perform quicker to road conditions without sacrificing ride comfort. This combination of valving and high pressure nitrogen gas keeps the tires in constant contact with the road helping to ensure safety through enhanced control.
Bilstein Gas Pressure Struts
Monotube struts will also provide superior stability through outstanding resistance to lateral forces.
Bilstein’s twin tube strut assemblies are manufactured with the extreme attentiveness to precision and detail that Bilstein is famous for. They are designed to withstand extremely highly loads while providing maximum durability.
And like our shock absorbers, Bilstein Struts are built for specific application.
Bilstein Gas Pressure Strut/Inserts function on the same principle as our normal gas pressure shock absorber. In the standard McPherson strut (which is based on the use of the twin tube shock absorber) the piston rod extends above the McPherson strut assembly and fastens to the sprung mass of the vehicle. In this type of application the piston rod has to absorb both the compression and rebound forces as well as tremendous side loads.
The uniqueness of Bilstein is to assemble the strut/insert with the rod pointing downward into the strut tube, therefore utilising the thicker, stouter body portion of the shock absorber to dissipate side loads (see sketch). In short, due to the increased diameter and surface of the pressure tube, the Bilstein Gas Pressure Strut/Insert is better suited to take increased side loads when compared with the conventional twin tube strut/insert.
The Bilstein Gas Pressure Strut/Insert, whose research and developent was influenced heavily by motorsport, has many other advantages as well, such as greater stability, accurate steering and better road handling. When you combine this Bilstein’s extremely high quality manufacturing and material selection, Bilstein will last approximately four times as long as some original replacement inserts.
Better By Design
Heat is known as one of the major detriments to the performance and longevity of any shock absorber. Conventional designed shocks trap the heat within the shock body and preventing adequate dissipation, making them prone to heat build up, fade and then the eventual failure.
Bilstein’s technically superior, patented monotube gas powered design allows the excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently. The dividing piston also permits the oil to expand as heat builds, preventing foaming and viscosity loss. In turn this allows the shock absorber to maintain full damping characteristics when the temperatures rises.
Superior Monotube Design & Fabrication
The tube of a Bilstein Gas Pressure Shock Absorber is fabricated using a special extrusion method. This process achieves an extremely tight peak-to-valley tolerance and maintains consistent wall thickness. Bilstein’s seamless monotube design provides superior tube strength while maximising heat dissipation and shock life.
Digressive Working Piston Assembly
Bilstein’s piston head design allows separate tuning of the compression and rebound damping forces to provide optimum ride comfort and performance without compromise. It features fewer parts than most conventional twin tube and “road sensing” shock designs. This functional simple digressive design adds to the long life and extreme durability of Bilstein Shock Absorbers.
Most conventional shocks are made with shock bodies cut from a piece of steel tubing, stamped internal parts and therefore compromised tolerances.
However Bilstein’s shock bodies are precision formed through a one of a kind seamless extrusion process. This gives you superior strength along with high finish tolerances that are usually associated with medical instruments. The shock body is then coated with a special paint finish, which is durable enough to withstand gruelling 240-hour salt spray tests. This finished body has a solid, induction hardened steel chrome plated and polished shaft, machined valving components and highest quality seals. Combined with there extreme attention to detail, Bilstein produces the closest thing to a hand-built shock available on the market today.
