dual needle & digital Air pressure gauge kit for air ride suspension, air bag, air brake

Air pressure is essential for any vehicle equipped with an air brake or an aftermarket air suspension system. Because air pressure directly affects the way the vehicle works, it is very important to monitor and adjust the air suspension pressure. If you are driving under insufficient pressure, your vehicle may be too close to the ground and the parts under the vehicle may not be lined up correctly, resulting in damage to the vehicle. If you drive when the air pressure in the air tank or air bag is too high, the excessive pressure may cause the parts to explode. To maintain the height and quality of the vehicle, it is essential to have an air suspension pressure gauge to monitor the air suspension system.
