Frequently Asked Questions About International 4700-4900 Front Axle Air Ride Kits

Will these air ride kits fit my specific International 4700 or 4900 model year?

Our front axle air ride kits are designed to fit International 4700 and 4900 series trucks from 1989 through 2007. However, compatibility can vary based on your truck's specific configuration, including axle rating and suspension type. We recommend checking your truck's VIN and front axle weight rating before ordering. Most kits accommodate 10,000 to 14,000 lb front axles, but some specialty configurations may require custom modifications.

What tools and experience level are needed for installation?

Installation typically requires intermediate to advanced mechanical skills and takes 4-6 hours with proper tools. You'll need standard mechanic's tools, plus a floor jack, jack stands, torque wrench, and air line cutting tools. The most challenging aspects include removing the existing leaf springs and properly aligning the new air spring mounts. Many customers recommend having a helper, especially when positioning the heavier components. Professional installation runs $400-800 depending on your location.

How much will these air ride kits improve my ride quality and what's the typical lifespan?

Customers report a 60-80% improvement in ride quality, particularly noticeable on rough roads and when running empty. The air springs significantly reduce cab bounce and driver fatigue on long hauls. With proper maintenance, including regular moisture draining and annual inspections, these kits typically last 150,000-250,000 miles. The air springs themselves usually need replacement every 5-7 years, while the mounting hardware and brackets can last the life of the truck.

What's included in the complete kit and will I need additional parts?

Complete kits include air springs, mounting brackets, shock absorbers, all necessary hardware, air lines, and fittings. However, you may need to purchase separately: a leveling valve (if upgrading from leaf springs), air tank and compressor upgrades (if your current system is undersized), and height control valves for adjustable ride height. Some installations also require new U-bolts if your existing ones are worn or the wrong size.

Can I maintain my truck's original ride height and load capacity?

Yes, these air ride kits are engineered to maintain your truck's factory ride height and front axle weight rating. The kits include adjustable mounting positions to fine-tune ride height within a 2-inch range. Load capacity remains unchanged from your original suspension rating, though the air pressure must be adjusted based on load weight. Most drivers run 60-80 PSI empty and 90-120 PSI loaded, depending on their specific axle rating and load requirements.
