A shock or damper is only as good as its adjacent components. We therefore advise that the complementary products for passenger cars, such as the top mounts, suspension springs for cars and service kits for cars, should be checked every time the shock absorbers are replaced. As a supplier of not only shock absorbers but also motor vehicle spares and components, SACHS is a leader in the segment of automobile suspension, providing high quality complementary products for any passenger cars.

Suspension springs for cars


What are suspension springs good for? Suspension springs are the connecting element between the wheels and the vehicle body. They support the weight of the vehicle and, together with the shock absorbers, ensure optimal road hold in all driving situations and under varying load conditions. Suspension springs for cars also compensate for bumpy roads and ensure good wheel-to-road contact. That makes them particularly important and safety-relevant motor vehicle spare parts. It is all the more important to replace broken suspension rings using high quality products.

If the suspension springs are defective, SACHS offers an extensive high-quality range of 3,100 products for the European and Asian vehicle markets, including suspension springs and other complementary products for passenger cars for all needs.

Service kits for cars


Service kits are part of the passenger-car complementary product range. They consist of compression stops or auxiliary springs and bellows or protective tubes and have the following functions:

  • Reducing chassis vibrations along with the shock absorbers, dampers and suspension springs
  • Protecting shock absorbers and suspension springs against overload
  • Protecting the shock absorbers' piston rod from salt residue, water, dust and dirt

Like all complementary products for passenger cars from the SACHS brand, the service kits are of the highest quality using state-of-the-art technology, and contribute considerably to the durability of the shock absorbers.

Suspension-strut mounts for PC (passenger cars)


Another complementary product for cars is the suspension-strut mount for PC. It forms the top mounting point of the shock absorber. At the same time, it supports the vehicle weight, enables steering depending on the axle design, and dampens rolling noises and vibrations. The suspension-strut mount is exposed to heavy stresses in day-to-day driving as well as to varying weather conditions. The consequences of a defect range from increased noise generation and longer stopping distances to the loss of precision wheel guidance. Therefore, we recommend replacing the suspension-strut mount when replacing the shock absorber.

Defective suspension-strut mounts lead to problems ranging from loss of precision wheel guidance, insufficient road contact and imprecise steering behavior to longer stopping distances, noise generation and vibrations.

Defective service kits lead to premature wear in shocks or dampers. Piston rod damage results in leakage of the shock or damper. What is more, defective service kits overload the suspension spring, causing faster wear of the suspension-strut mounts.

Defective suspension springs result in poor tracking stability. It becomes difficult to control the vehicle. Parts that break off the suspension springs can damage the tires. Moreover, defective suspension springs can lead to varying vehicle levels on one axle. Lastly, noises may occur during spring compression

Several situations can lead to breaking suspension springs, e.g. fluid leaks or wheel imbalances due to misalignment or damaged tires. In some situations, suspension springs break as the result of other components failing.

A high-quality suspension spring from SACHS weighs about 2 kg.

The durability of suspension springs depends on the state of its surrounding components as well as on the loads and conditions the chassis is subjected to. The state-of-the-art suspension springs from SACHS are extremely durable.
