International IH Cabover Air Springs-Valves

Frequently Asked Questions About International IH Cabover Air Springs-Valves

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

Air springs (also called air bags) support the cab or suspension and absorb road shock, while the leveling valve automatically adjusts air pressure in the springs to keep the cab or chassis riding at the correct height as loads shift. Together they help maintain a stable, level ride and reduce wear on surrounding components.

How do I know if my air spring or leveling valve is failing?

Common warning signs include a cab that sags to one side, a rough or bouncy ride, hissing or air leak sounds near the suspension or cab mounts, and the cab not returning to its normal ride height after hitting a bump. If you notice any of these symptoms, it is a good idea to inspect the air spring and valve linkage before they cause further drivetrain or cab mounting issues.

Will these air springs and valves fit my specific International IH cabover model?

Fitment can vary by year and model within the IH cabover lineup, so it is important to check the listed application details on each product page and compare them to your truck's VIN or existing part numbers. If you are unsure, our team can help confirm compatibility before you order.

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

Many drivers and shop technicians replace these parts with basic hand tools, a way to safely support the cab or chassis, and access to shop air. That said, because these components affect cab stability and ride height, we recommend following proper safety procedures, releasing air pressure before disconnecting anything, and consulting your service manual or a qualified technician if you are not comfortable with the job.

How long should an air spring or leveling valve last, and should I replace them in pairs?

Lifespan depends on mileage, load conditions, and exposure to road debris or extreme temperatures, so there is no fixed replacement interval. If one air spring or valve has failed due to age or wear, the other side has likely seen similar use, so many drivers choose to replace both sides at the same time to maintain even ride height and avoid a repeat repair soon after.
