Vehicle modified shock absorber spring
Racing Spring (Green)
Z70

1. Spring material
Using special high-strength steel wire H5S/TW (tensile force = 2000N/mm2). In addition to having excellent fatigue resistance and fatigue resistance, significant weight reduction is also achieved.

2. Spring characteristics
Use in high stress areas is achieved by raw machining. Flexibility and toughness can be obtained.

3. Significant weight reduction improves athletic performance
By reducing the weight of the spring, the return speed (recoverability) is increased by about 10% compared to the past. Achieve road following, faster body stability and smooth steering when cornering.

4. Ensure stable spring constant and large stroke
Improve spring constant accuracy in application areas with our unique technology. It provides a comfortable ride and lightens the tires.
Measurement results: within 30% to 70% of maximum allowable travel → spring constant tolerance within ± 3%

When using Swift spring
Since quick springs do not have allowable travel until close contact between the wires, check the shock travel and allowable travel of quick springs before choosing a free length. Also, even within the allowable travel range, you can experience the difference between a traditional product and a Swift spring if you leave room for travel and use the free length one size longer.

Note: If the main spring is used in close contact (full compression), it will not only damage the original spring performance, but also have the risk of sagging, deformation or breaking, please use it within the load range.
