Frequently Asked Questions About International S1700-S1900 Air Springs & Valves

Will these air springs fit my specific International S-Series truck model and year?

Our air springs and valves are designed to fit International S1700, S1800, and S1900 models from 1979 through 2001. However, compatibility can vary based on your truck's specific configuration, suspension type, and whether it has been modified. We recommend checking your existing part numbers or contacting our support team with your VIN to ensure proper fitment. Many S-Series trucks came with different suspension options from the factory, so verification is important to avoid returns.

How difficult is it to install these air springs, and what tools will I need?

Installation typically takes 2-4 hours per axle for someone with basic mechanical skills. You'll need standard hand tools, jack stands, and ideally an air compressor for testing. The most challenging part is often removing the old, corroded springs and mounting hardware. Many customers report that having a helper makes the job much easier, especially when aligning the new springs. Professional installation usually runs $200-400 if you prefer not to DIY. Always follow proper safety procedures and support the frame properly during installation.

What's the difference between OEM-style and aftermarket air springs for my S-Series?

OEM-style air springs match original specifications and mounting points exactly, ensuring direct bolt-on installation. Aftermarket options often feature upgraded rubber compounds or reinforced construction for longer life, though some may require minor modifications to mounting brackets. The main differences you'll notice are in price (aftermarket typically 30-50% less), warranty coverage, and sometimes load capacity. Both types work well, but OEM-style parts guarantee the easiest installation.

How long do these air springs typically last, and what causes premature failure?

Quality air springs generally last 80,000-150,000 miles under normal use. The most common causes of early failure include road salt corrosion, overloading beyond capacity, running with inadequate air pressure, and contaminated air systems. Regular inspection for cracks, proper inflation, and keeping the air system moisture-free will maximize lifespan. Many drivers in northern states report getting only 3-5 years due to road salt, while those in drier climates often see 7-10 years of service.

Do I need to replace the leveling valves when changing air springs?

While not always necessary, replacing leveling valves during air spring service is recommended if they're over 5 years old or showing signs of wear. Common symptoms of failing valves include uneven ride height, slow air leaks, or the truck not leveling properly under load. Since you're already doing the work, many customers choose to replace valves preventatively to avoid another service call. A complete kit with springs and valves typically saves money versus buying components separately later.
