SACHS shock absorbers are produced by the German group ZF Friedrichshafen AG. Under the SACHS brand several types of shock absorbers are produced: monotube, twin-tube, with adjustable road clearance, strut assemblies. They are all premium class. They are installed as original parts in the assembly of most car models. Half billion SACHS shock absorbers are manufactured every year."

Every year, over 10 million new cars roll off the assembly line fitted with SACHS auto shocks. Equally, SACHS applies its OE expertise to spare parts production, so its aftermarket car shock absorbers are always state-of-the-art, which means a safer, more comfortable and contemporary drive.
No matter what challenges the road presents, the chassis performance and dynamics SACHS aftermarket shocks provide ensure perfect road grip and cornering.


SACHS has a car shock absorber for every requirement, e.g. monotube and twin-tube dampers, suspension struts, spring carriers (shock absorbers with spring plate) and suspension cylinders (auto shocks with hydraulic leveling system). Upgrade your vehicle's suspension with 317 645 SACHS Shock Absorbers and experience a smoother, safer ride.
- The SACHS monotube damper can be installed in any position. It operates at higher pressure than the twin-tube damper
- The twin-tube damper has a shorter installation length than its monotube equivalent
- SACHS CDC dampers (Continuous Damping Control) for passenger cars stand for perfect damping in any situation. State-of-the-art technology continually records all the variables that are relevant to damping and adjusts the damping force to the external conditions using a valve. The damping force is varied depending on the road condition, payload weight or vehicle handling.
