Frequently Asked Questions About International LT Air Springs & Level Valves

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

Our air springs are designed to fit International LT models from 2017 to present. However, compatibility can vary based on your specific suspension configuration (standard vs. air ride) and whether you have a day cab or sleeper. We recommend checking your existing part numbers or calling our technical support team with your VIN to ensure proper fitment before ordering.

How difficult is it to install replacement air springs and level valves?

Most experienced mechanics or skilled DIYers can complete the installation in 2-4 hours with basic hand tools and a floor jack. The process typically involves supporting the chassis, removing the old air spring, and installing the new one with proper torque specifications. Level valve installation requires additional air line connections and height adjustment. We strongly recommend having a service manual on hand and following manufacturer torque specs for all hardware.

What's the difference between OEM and aftermarket air springs for my International LT?

OEM air springs are manufactured to exact International specifications and typically last 5-7 years under normal conditions. Quality aftermarket options from brands like Firestone and Continental often match OEM performance at 30-40% less cost. The main differences are warranty coverage (OEM usually offers longer warranties) and minor variations in rubber compound formulation. Both options will maintain proper ride height and load capacity when properly installed.

How do I know if my level valve needs replacement versus just adjustment?

A properly functioning level valve should maintain consistent ride height regardless of load. Signs of failure include: truck leaning to one side, constant air loss when parked, or inability to maintain height under load. Before replacement, try adjusting the linkage arm - if the valve still cycles continuously or won't hold air, replacement is necessary. A simple soap bubble test on the exhaust port can confirm internal seal failure.

Are there different air spring styles for various suspension setups on the International LT?

Yes, International LT trucks come with either rolling lobe or convoluted (bellows-style) air springs depending on the suspension package. Rolling lobe springs are more common on standard suspensions and offer a smoother ride, while convoluted styles are often found on heavy-haul configurations. Each style requires specific mounting hardware and has different compressed and extended height specifications. Always match the style to your existing setup unless converting the entire suspension system.
