International RH Air Springs & Level Valves

Frequently Asked Questions About International RH Air Springs & Level Valves

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

Air springs (also called air bags) are part of the suspension system that supports the weight of the truck and cab, providing a smoother ride and helping maintain consistent ride height. The level valve monitors ride height and automatically adjusts air pressure in the springs to keep the suspension properly leveled as loads change. Together, these components help maintain handling, stability, and ride comfort.

How do I know if I need a replacement air spring or level valve?

Common signs include a sagging or uneven ride height, a bouncy or rough ride, visible cracks or bulges in the air spring bellows, audible air leaks near the suspension, or the truck leaning to one side. If the cab or axle sits noticeably lower than normal or the suspension takes longer than usual to level out, the level valve linkage or valve itself may need inspection or replacement.

Will this air spring or level valve fit my specific International model?

Air springs and level valves are often model and application specific, so it is important to confirm fitment based on your truck's year, model, and axle or suspension configuration before ordering. Check the listed part number against your OEM part or consult your truck's service manual. If you are unsure, reach out to our team with your VIN or current part number and we can help confirm compatibility.

Can I install a replacement air spring or level valve myself, or should I have a professional do it?

Some experienced DIYers with the right tools are able to replace air springs and level valves themselves, especially if they are familiar with truck suspension systems. However, these components involve pressurized air lines and structural suspension parts, so improper installation can affect ride height, handling, and safety. If you are not confident working with air suspension systems, we recommend having the installation performed by a qualified technician.

What is the difference between OEM and aftermarket air springs and level valves, and does it matter?

OEM parts are made to match the original manufacturer specifications for your International truck, while aftermarket parts are produced by other manufacturers to fit the same applications, often at a different price point. Quality can vary between aftermarket brands, so it is worth checking the materials, warranty, and reviews for the specific part you are considering. Both OEM and reputable aftermarket options can be reliable choices depending on your budget and preference.
