Purpose: To adjust the car height quickly, easily and independently to make the car meet the requirements for driving under different road conditions and hourly speeds.

1. Select a proper damping force to improve the riding comfort;

2. The oil seal is organized by NOK and it is more enduring thanks to the automatic compensation technique;

3. The unique technique ensures high strength and excellent bending resistance for the piston rod;

4. During inflation, phenomena like air bubbles, resistance idle running and discontinuity are basically avoided, improving the riding comfort of the entire car and car handling under high speed;

5. The spring tower’s height may be adjusted with a spanner. In this way, the distance between the car and ground may be adjusted conveniently and independently, making the car meet the requirements for driving under different road conditions better;

6. The slanting and sideslip phenomena of the car during high-speed driving may be improved. The improvement effect is more obvious when the car is in curve-way running.
