1. Adopting the principle of buffering, the shock absorption performance is obviously improved 2. When passing through bumpy roads and sharp turns, the stability is significantly improved 3. Restrain the vibration of the vehicle body caused by the uneven road surface during the driving process of the car, thereby reducing the vibration noise during the driving of the car 4. Appropriately increase the height of the car body to improve the passing performance of the road obstacles of the car 5. Protect shock absorbers and suspension systems, prolong the life of automobile shock absorbers, and prevent shock absorber spring oil seal damage caused by excessive bump strength 6.
