DESCRIPTION

Some of the drawbacks of air suspension systems are because of some of the mechanical issues they can be vulnerable to. Several of the common issues with air suspension systems that can require repair include:

• Rust or moisture damage from the inside that can lead to the air struts or bags to malfunction
• Failure of the air suspension tubing connecting the air struts or bags to the air system
• Air fitting failure resulting from initial fitting or infrequent use
• Compressor burn out due to air leaks in the springs or air struts from the compressor constantly engaging to maintain the proper air pressure

Air suspension systems seem even more mysterious but, as it turns out, they aren't a whole lot different. Most modern suspensions are made up of a coil spring that slips over a shock or is positioned near it. At its core, an air suspension really just does away with those coil springs for flexible, pressure-filled bags of air that are typically made of the same sort of rubber as your tires. At the touch of a button, the bags can be inflated or deflated, instantly altering ride height and how the suspension performs.

Bellows-style air springs are made from heavy-duty, reinforced rubber which is configured with either one or more convoluted chambers.

These air bags are typically larger than sleeve-style air springs, giving them greater load-handling capacity. Because of their size and shape, bellows-style air springs can lift the same weight with about half the air pressure of sleeve-style springs.

The most popular bellows-style air spring configurations include single, dual, and triple chamber design. Bellows air springs are great for heavy-duty applications as long as there is plenty of space for proper installation.
