Frequently Asked Questions About International 9300/9370 Front Axle Air Ride Kits

What year models of International 9300 and 9370 trucks are compatible with these air ride kits?

These front axle air ride kits are designed to fit International 9300 models from 1987-2003 and International 9370 models from 1994-2003. However, compatibility can vary based on your specific front axle configuration and GAWR (Gross Axle Weight Rating). We recommend checking your truck's VIN and axle specifications before ordering, or contact our support team with your truck details for verification.

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

Installation typically takes 4-6 hours for experienced mechanics and 6-10 hours for DIY installers with moderate mechanical skills. You'll need standard shop tools including jack stands, air tools, torque wrench, and basic hand tools. The kit includes detailed instructions, but you'll need to remove the existing leaf springs and hangers. Many customers report that having a second person helps significantly during spring removal and air bag positioning. Professional installation runs between $400-$800 depending on your location.

What is the actual ride improvement and load capacity of these air ride systems?

These kits typically provide a 60-70% improvement in ride quality compared to standard leaf springs, significantly reducing cab shake and driver fatigue on rough roads. Most kits support 12,000-14,000 lb front axle ratings, though some heavy-duty options go up to 16,000 lbs. The adjustable air pressure (typically 40-100 PSI) allows you to fine-tune the ride based on your load, providing both empty and loaded ride optimization that leaf springs cannot match.

What maintenance is required, and how long do the air bags typically last?

Air bags generally last 100,000-150,000 miles with proper maintenance, though some drivers report 200,000+ miles in ideal conditions. Regular maintenance includes checking air pressure weekly, inspecting for leaks monthly, and keeping the bags clean from road debris and chemicals. The most common failure point is the air lines and fittings (not the bags themselves), which should be inspected every 6 months. Keep spare air line and push-to-connect fittings on hand for quick roadside repairs.

Do these kits include everything needed for installation, or are additional parts required?

Most complete kits include air bags, mounting brackets, air lines, fittings, and basic inflation valves. However, you'll typically need to purchase separately: an on-board air compressor (if your truck doesn't have one), air gauges for cab mounting, and potentially new shock absorbers if yours are worn. Some installations may require frame modifications or reinforcement plates depending on your truck's condition. Budget an additional $200-$500 for these supplementary components to complete your installation properly.
