Sachs strut assemblies utilize a twin-tube system with gas or hydraulic damping to absorb road imperfections and maintain vehicle stability. The strut serves as the mounting point for the steering knuckle, allowing the front wheels to turn smoothly while keeping the wheels firmly planted to the road surface. Protected by bellows and bump stops, the strut's internal seals are shielded from dirt and debris to ensure long service life.

As part of the ZF family of brands, Sachs serves as an OEM supplier to manufacturers including BMW, Audi, Porsche, and Volvo. All Sachs components are engineered to meet or exceed original equipment specifications. Professional installation is recommended, and struts should be replaced in pairs to maintain balanced handling characteristics.
