Strut Parts

Spring, Strut Mount, Dust Cover, Buffer, all of them are important parts of shock absorber strut.  The spring resistance of suspension spring strictly are checked and controlled, and each batch performs the performance check of permanent deformation.  Strut Mount play a buffer action and nimble balance rotation bearing. Dust Cover protect from the surface of the shock absorber from outside corrosion and damage.  Buffer reduces impact to protect parts. 


  • The suspension coil spring is used to support car body, to relieve the vabriation by the uneven ground and keep tyre onto earth closely.
  • The material for suspension spring adopts high quality alloy spring steel 55CrSi after oil quenching.
  • Various testing for springs such as strength testing, crush test and endurance test to assure the high quality.

Strut mount:

  • High strength & good cushion rubber material.
  • Excellent bonding between rubber and metal.
  • Nimble balanced rotation bearing.
  • High strength steel material.

Dust Cover:

  • Dust cover is to prevent dust and chips, to reduce particulate hard foreign object damage to the shock absorber.
  • It is oil resistance, good aging resistance and service life.


  • Buffer is made of rubber or foamed polyurethane. Most modern cars' buffers are made ​​of porous polyurethane, rubber material which is gradually being replaced.
  • Foamed urethane rubber is made ​​of natural rubber to ensure as hardness, static stiffness, life in accordance with the relevant standard parts durability test of 400,000 times.
