No coil-to-coil contact under. Whit the help of a spring tester, technical data sheet is drawn up with all parameters for new springs which are to be developed. High levels of comfort and safe handling. All Suplex springs are provided with a zinc phosphate coating, which is primarily to keep the epoxy powder coating in robust state.
A prototype is created based on these parameters, which has to go through a few test procedures before the spring goes into production. The highest quality chrome vanadium and silicon alloy steels. These test mainly consist of telegraphic examinations, mechanical material tests and longevity. Phosphate coating to protect the spring steel from corrosion.
Carefully controlled shot preening process significantly increases the fatigue life of spring. Manufactured using modern CNC-winding machines, the springs made by Suplex deliver excellent performance and uncompromising dependability. Suplex springs are shot-preened in order to compact the surface and extend longevity. Features: Progressive Spring rate.
Rear Passenger Side Coil Spring 06164 by Suplex. The process is described as stress treatment or exposure. Tough, epoxy powder coating protects the underlying spring steel from mechanical damage. They are provided with a zinc phosphate coating to prevent corrosion.
Surface coating. The zinc phosphate coating prevents the corrosion of spring steel. Quantity: 1 per Pack. Suplex goes one step further and subjects the spring to treatment whilst it is assembled.
Research and development. Shot-preened and stress-preened. Replaces Original OE Part #: 06164. Specifications: Type: Heavy Duty.
