How do Air Shocks Work?
Air shocks work just like normal shocks. They are designed to withstand compression and damping forces. When you hit a bump in the road, your suspension compresses. The suspension then rebounds back to normal. Damping refers to how the suspension handles these compression and rebound forces after you hit a bump in the road. Heavy loads may cause compression and rebound forces to overwhelm your factory suspension. To haul heavy loads safely, you may need to install a pair of air shocks, as well as heavier springs on your rear suspension system.
Air shocks include metal fittings, a plastic air hose, and a Schrader valve to allow you to fill them with air after installation. An air shock pump or even a simple bicycle pump may be used to fill your air shocks. Air lines must be purged of moisture periodically as part of a regular maintenance routine.
