International WorkStar Air Springs & Level Valves

Frequently Asked Questions About International WorkStar Air Springs & Level Valves

What do air springs and level valves actually do on my International WorkStar?

Air springs support the weight of the cab or suspension and provide a cushioned ride by adjusting air pressure as load changes. The level valve works with the air springs to automatically regulate air pressure, keeping the vehicle riding at a consistent height regardless of load. Together, these components help maintain ride quality, stability, and proper axle alignment.

How do I know if my air spring or level valve needs to be replaced?

Common signs include a sagging cab or chassis, an uneven ride height from side to side, a rough or bouncy ride, visible cracks or bulges in the air spring bellows, or audible air leaks near the suspension or cab mounts. If you notice the truck settling lower over time or leaning to one side, the level valve linkage or the air spring itself may be worn out.

Will these air springs and level valves fit my specific WorkStar model and year?

Fitment can vary by model year, cab configuration, and whether the part is for the cab suspension or chassis suspension. Always check the listed part number and specifications against your truck's VIN or existing OEM part number before ordering. If you are unsure, our team can help confirm fitment based on your truck's details.

Can I install a replacement air spring or level valve myself?

Many experienced DIY mechanics and fleet technicians replace these parts themselves, but the job typically involves working with the truck's air system, so a basic understanding of air brake and suspension systems is helpful. You will need to safely support the vehicle, relieve system air pressure, and properly reconnect and adjust the level valve linkage afterward. If you are not comfortable working around air systems, having a qualified technician handle the installation is recommended.

Are these air springs and level valves OEM or aftermarket, and what is the quality difference?

Our catalog includes both OEM and quality aftermarket options. OEM parts are built to match the original manufacturer's exact specifications, while aftermarket parts are manufactured to fit and function similarly, often at a lower cost. Each product listing notes whether the part is OEM or aftermarket so you can choose based on your budget and preference for original equipment matching.
