International LT Air Springs & Level Valves

Frequently Asked Questions About International LT Air Springs & Level Valves

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

Air springs (also called air bags) are the rubber and steel components that support the weight of the cab or suspension and absorb road vibration, providing a smoother ride and reducing stress on the frame. The level valve works alongside the air springs to automatically adjust air pressure, keeping the cab or axle riding at the correct height regardless of load. Together, these parts help maintain ride quality, stability, and proper alignment.

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

Common signs include a cab that sits noticeably lower on one side, a rougher or bouncier ride than usual, visible cracking, bulging, or leaking on the air spring, and a hissing sound coming from the suspension area. If the cab height seems inconsistent or slow to level out after hitting a bump, the level valve linkage or valve itself may need to be inspected or replaced.

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

Fitment can vary depending on the model year, cab configuration, and whether the part is for the front or rear suspension. We recommend checking the listed part number and specifications against your truck's build sheet or OEM part number before ordering to make sure you get the correct fit.

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

Many experienced truck owners and fleet technicians replace air springs and level valves themselves, since the job typically involves basic tools, supporting the cab or axle safely, and reconnecting air lines and linkage. That said, because these parts are tied to ride height and cab stability, if you are not comfortable working around air suspension components or lack the proper jack stands and safety equipment, having a qualified technician handle the install is a safer choice.

Are these parts OEM or aftermarket, and does that affect quality?

Our listings include a mix of OEM and quality aftermarket air springs and level valves. Aftermarket parts are manufactured to match OEM specifications and are generally a reliable, cost-effective alternative, but if you prefer to match your truck's original equipment exactly, check the product description for OEM part number cross-references before purchasing.
