Information on Air Ride Suspension

Function

Interior switches allow drivers to rise, lower,soften or harden the air springs. At speed, a lower ride height can increase aerodynamics and keep a vehicle more stable. Commercial trucks that carry heavy loads can benefit from decreasing ride height when unloading, loading and attaching to a hitch.  



Components

Air ride suspension is made of multiple components: compressor, air storage tank, valves, pressure switch, air filter, airlines, air springs, switchboxes, gauges, fittings and hardware. The pressure switch controls when the compressor turns on and off, which maintains adequate air pressure for ride height adjustments. An air filter keeps dust, moisture and grime out of the system. Valves act as the control center for the air

springs.


Application
Air ride suspension is useful for any vehicle that requires ride height adjustment periodically. In popular culture, air ride suspension is an alternative to hydraulics used by low rider enthusiasts. Commercial 18-wheel trucks use air ride suspension for increased cargo safety. Trucks that haul items such as a boat, trailer or camper can benefit from air ride suspension when connecting the hitch.


Maintenance

The air compressor creates moisture as it heats up and then cools down. While the air filter will take care of some of this moisture, water will still build up in the air tank over time. Draining this water once a month will keep your air ride suspension working properly.


Safety

Never install copper lines in the place of stainless steel or nylon air lines because copper requires additional maintenance, does not absorb vibration well, and can break down leading to system failure. When installing nylon and rubber air springs be cautious--you can puncture them on chassis components. Also, make sure that the air springs can fully inflate and deflate freely. Verify that your battery can handle the extra wattage associated with a specific system to avoid electrical failures.
