The material for suspension spring adopts high quality alloy spring steel 55CrSi after oil quenching, material strength and fatigue resistance of which is more than 20% higher than the 60Si2Mn material used by the average manufacturer in the market.

    The spring resistance of suspension spring strictly are checked and controlled, and each batch performs the performance check of permanent deformation. Furthermore, we strictly control the height and stiffness of the spring.


    Advantages of LEACREE springs:

    Quality high strength alloy material

    Advanced producing techniques

    100% flaw detection inspection and complete test methods to keep safety

    High performance and long lasting life time
