A shock or damper is only as good as its adjacent components. We therefore advise that the complementary products in passenger cars, such as the top mounts, service kits and suspension springs, be checked every time the shock absorbers are replaced.

Suspension springs for passenger cars

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 also compensate for bumpy roads and ensure good wheel-to-road contact. That makes them particularly important and safety-relevant spare parts for vehicles.

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

Passenger car service kits

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 vibrations along with the shock absorbers 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 passenger-car complementary products from the SACHS brand, the service kits are of high quality. They contribute considerably to the durability of the shock absorbers.

Suspension-strut mounts for passenger cars

Another complementary product is the suspension-strut mount. 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 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.

FAQs about complementary products

Damage evaluation – How can I detect defective complementary products?

The visual inspection provides information about the components' condition.

Worn service kit (left) and new service kit (right).

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.
