the Technology of BILSTEIN’s Monotube Design
Bilstein monotube shocks are the perfect choice for those who demand the most from their vehicle. The monotube technology provides greater damping power due to the larger surface area of the piston. This results in improved handling, consistent performance, and longer service life. They use this technology in many of their popular series such as the Bilstein 5100, Bilstein 4600 and Bilstein HD Shocks.
Heat is one of the major detriments to the performance and longevity of any shock absorber. Conventional twintube designed shocks trap the heat within the shock body and do not let it adequately dissipate, making them prone to heat build-up, fade and eventual failure. When under movement or pressure, the fluid starts foaming leading to poor ride quality. By contrast, Bilstein’s superior monotube high gas pressure 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 aeration (foaming) and viscosity loss. This allows the shock to maintain full damping characteristics as temperatures rise.
