Sachs shock absorbers feature a twin-tube design with separate working and compensating cavities filled with hydraulic oil and pressurized gas. This construction provides superior damping control to reduce body roll, improve tire contact with the road surface, and enhance overall vehicle stability. The precision valve system effectively controls both compression and rebound rates for a balanced ride that maintains comfort while improving handling dynamics.

As part of the ZF Aftermarket family of brands, Sachs shock absorbers benefit from over a century of engineering expertise and motorsports-proven technology. Each unit is manufactured from high-quality materials and undergoes rigorous testing to ensure it meets strict OE specifications for safety, performance, and durability.
