The Sachs Shock Absorber Kit - 140786 is a comprehensive set of products designed to improve the performance and stability of a car's suspension system. It includes four shock absorbers, four coil springs, four bump stops, and four dust covers. These components work together to absorb and dampen the impact of bumps and vibrations on the road, providing a smoother and more comfortable ride for the driver and passengers. The shock absorbers are responsible for controlling the movement of the suspension, while the coil springs support the weight of the vehicle and help maintain its height. The bump stops prevent the suspension from bottoming out, and the dust covers protect the components from dirt and debris. This kit is an essential upgrade for any car owner looking to improve their driving experience and ensure the longevity of their suspension system.
