In air-suspension systems, air springs replace coil springs. The system uses an onboard compressor, which is an electric pump, 

To feed air to the bags through multiple lines. The compressor pulls outside air into the pump, compresses the air and transfers it to the bags.

Keep adjusting the height between vehicle tires and road. Restore your vehicle original ride, and improve driving performance. 

Reduce vehicle bounce, roll and sway, brake dive, and acceleration squat.

Adopt standardized design, unified manufacturing and quality control system to ensure the consistency of damping

Attention

To avoid the possibility of short circuits while working with electric components consult your owner's manual on how to disconnect your battery.
Consult your vehicle owner's manual, service manual, or car dealer for the correct jacking points on your vehicle and for additional care, 

safety and maintenance instructions. Under no circumstances should any work be completed underneath the vehicle

Note

1)Unusual Noise
As shocks and bushings wear, struts bottom out and make metal-to-metal contact
2)Hydraulic Oil Seepage
The seals have broken and the internal fluids essential to proper function are escaping
3)Tire Cupping or Scalloping
The tires recoil faster, there can be patterns of wear that alternate
4)The Front End Dives and/or the Rear Squats
This happens when shocks and struts aren’t strong enough to handle the weight of the vehicle
5)Vehicle "Tips" To One Side in Turns
Driving with bad shocks or struts can increase your stopping distances
6)Instability at Highway Speeds
Your vehicle never feels completely stable on the highway and is constantly moving up and down
