Frequently Asked Questions About International IH Cabover Front Axle Air Ride Kits

What International Cabover models are compatible with these air ride kits?

Our air ride kits are designed to fit International CO4070, 9670, 9700, and 9800 series cabovers. The kits are specifically engineered for models from the late 1970s through the 1990s. Before ordering, verify your exact model year and axle configuration, as some variations may require additional brackets or modifications. If you're unsure about compatibility, contact us with your VIN number for verification.

How difficult is the installation process, and what tools are required?

Installation typically takes 6-8 hours for experienced mechanics and requires standard shop tools including air tools, torque wrenches, and basic hand tools. The most challenging aspects involve removing the existing leaf springs and properly aligning the new air bags. You'll need a minimum 2-post lift or jack stands rated for commercial trucks. Many customers report that having a helper makes the installation significantly easier, especially when positioning the heavy components. Professional installation is recommended if you lack experience with suspension work.

What's included in the complete kit, and are any additional parts needed?

Each kit includes air bags, mounting brackets, air lines, fittings, and detailed installation instructions. However, you'll need to purchase separately: an air compressor system (if your truck doesn't have one), air gauges for cab monitoring, and potentially new shocks designed for air ride systems. Some older trucks may also require frame reinforcement plates depending on condition. The kit does not include leveling valves, which are sold separately based on your specific ride height preferences.

What are the actual ride quality improvements I can expect?

Drivers typically report a 60-70% reduction in cab bounce and vibration compared to worn leaf springs. The air ride system provides adjustable firmness, allowing you to fine-tune the ride based on load conditions. Most notably, the system dramatically reduces driver fatigue on long hauls and minimizes cargo shifting. The improvement is most noticeable on rough roads and when running empty. Keep in mind that worn shocks or other suspension components can limit the effectiveness of the air ride conversion.

What maintenance is required, and how long do these systems last?

Air bags typically last 100,000-150,000 miles with proper maintenance. Check air pressure weekly and inspect for leaks monthly. The rubber air bags should be cleaned quarterly with soap and water to prevent dry rot. Most failures occur from road debris damage rather than wear. Keep spare air line fittings on hand for quick repairs. The mounting brackets and hardware are built from heavy-duty steel and should last the life of the truck with minimal maintenance beyond checking bolt torque annually.
