SACHS Strut and Spring Assemblies are constructed and tested using premium quality components. Our SACHS Struts are intelligently engineered to restore original handling dynamics while designed to meet the highest safety, comfort, performance, and quality standards. SACHS products have the best dampening properties with an application-tuned valve pairing longevity with superior comfort and control for vehicles in any road condition. A strut is a special type of shock absorber that is designed to rotate with the motion of the steering, and directly connect to the steering knuckle. Because the strut rotates on an axis, the coil spring is integrated into the design, and mounted as a complete independent assembly with strut mounts and a bearing that the assembly rotates on. Signs of worn out shocks include a bouncy ride when driving, as well as more noticeable body roll in turns. Routine inspections will indicate if your shocks are leaking or damaged.
