KW spring strut construction

Advantages of a KW coilover spring strut at one glance:

  • Optimally adjusted KW suspension for any car class and any use – comfortable, sporty or performance-oriented
  • High-quality components for long durability
  • Innovative technology of the separately adjustable rebound- and compression damping
  • Use of double-pipe technology, therefore separate adjustment of the damping forces for target-oriented influence of the car body vibrations and drive dynamics
  • Pre-set suspension with all component parts, vehicle-specific certificate and plain assembly instruction

Aluminium Strut mount


Polyamide spring plate

  • Low weight
  • noise-absorbing composite material reduces vibration sounds and isolates rolling noises from the car body
  • absolutely corrosion-resistant

Compression buffer with integrated dust protection system

  • Compression buffer/additional spring made of high-quality elastomer synthetic
  • Integrated dust cap, protection from dirt, stone-chipping and splash water
  • Highly resilient and low wear susceptibility

Pre-stressed spring made of flat wire

  • Allows pre-stressing the main spring over the entire adjustment range
  • Minimal total height and optimal force closure

High-strength springs

  • Weight- and construction space optimised spring constructions
  • Multi-level tempering process (annealing, shot blasting, jigging, UV-test, phosphate coating, EPS coating) for optimal durability and minimised jigging characteristics

Polyamide ring nut

  • noise-absorbing effect

"inox-line" stainless steel spring strut casing

  • 100% corrosion-resistant in all environments
  • Dirt-resistant trapezoid thread allows easy adjustment even when spring is pre-stressed
  • noise-absorbing effect
  • Visually appealing and unlimited durability

Aluminium strut mount

Adjustable strut mount made of high-strength aluminium are optionally available (where technically expedient) in our Clubsport suspensions. A special sealing system prevents the intrusion of dirt and splash water into the free-of-play pre-stressed uniball bearings and therefore prevents corrosion and wear.
  • Scaled camber adjustment (optionally also caster)
  • Sealed, in load direction pre-stressed uniball bearing
  • Made of tool steel (100Cr6); 58 to 64HRC – hard chrome plated, PTFE lubrication layer, stainless steel outer ring (X20Cr13)
  • Axial bearing as rotation balance at McPherson strut mounts

Polyamide ring nut

The extremely light spring plates which are made of polyamide composite material are absolute corrosion-resistant and due to a trapezoid thread they can be even easily adjusted when the strut is pre-stressed.
  • Polyamide composite material with perfect sliding characteristics
  • Stainless steel layer for enforcement and as condensation protection for the struts
  • Noise-absorbing effect
