SACHS shock absorbers are of the highest quality, which is one reason why numerous well-known automotive manufacturers fit them as standard in new vehicles. No matter what challenges the road presents, the chassis performance and dynamics SACHS aftermarket shocks provide ensure perfect road grip and cornering.

A passenger car shock absorber, together with the coil spring, forms the end link between the suspension and the vehicle body. It is a vital safety-related component that reduces vibrations in the suspension spring, slowing it down and thus reducing vehicle body movement.


The SACHS twin-tube damper 2-556 275 has two oil-filled cavities: the working cavity in which the piston and piston rod move, and the compensating cavity. The compensating cavity is located between the working cylinder and the reservoir tube, and is filled 2/3 with oil and 1/3 with air or gas. As a result, the twin-tube damper has a shorter installation length than its monotube equivalent.
