Frequently Asked Questions About International S2200-S2600 Front Axle Air Ride Kits
Will these air ride kits fit my specific International truck model and year?
These air ride kits are designed specifically for International trucks with S2200 through S2600 front axles, commonly found in 4300, 4400, 7300, 7400, 7500, 7600, 8500, and 8600 series trucks from 2002-2018. However, axle configurations can vary even within the same model year. Before ordering, verify your axle model number (stamped on the axle beam) and measure your current spring pack width and center-to-center mounting distances. Most kits accommodate standard 3-inch wide spring packs with 24-inch to 26-inch mounting centers.
How difficult is the installation, and what tools do I need?
Installation typically takes 4-6 hours per side for experienced mechanics. You'll need standard shop tools including a floor jack, jack stands rated for commercial trucks, impact wrenches, and basic hand tools. The most challenging part is safely supporting the axle while removing the leaf springs. Many customers report needing to slightly modify the upper mounting brackets for proper clearance, particularly on 7400 and 7600 series trucks. Professional installation is recommended if you're not comfortable working with heavy commercial suspension components.
What air pressure should I run, and do I need additional air system components?
Recommended air pressure varies by load but typically ranges from 60-90 PSI for most applications. You'll need an adequate air supply system - your truck's existing air brake compressor is usually sufficient, but you'll need to add air lines, fittings, a pressure protection valve, and gauge. Many customers also install a manual or electronic leveling system for optimal ride height control. The kit includes the air bags and mounting hardware, but air management components are sold separately.
How durable are the air bags, and what maintenance do they require?
Quality air bags typically last 100,000-200,000 miles with proper maintenance. The rubber compounds are designed to withstand road salt, oil, and extreme temperatures from -40?F to 200?F. Regular maintenance includes monthly visual inspections for cracks or abrasions, keeping proper air pressure, and ensuring mounting hardware stays tight. Most failures occur from running bags at incorrect pressures or from debris damage. Always maintain minimum pressure of 20 PSI to prevent bag damage from folding.
What's the actual ride improvement, and will it affect my truck's handling?
Drivers report 60-80% reduction in cab bounce and significantly less driver fatigue on long hauls. The air ride provides better shock absorption over rough roads and reduces stress on the chassis and cargo. Properly installed and adjusted, handling remains stable with improved cornering due to reduced body roll. Some drivers note slightly increased stopping distances when fully loaded due to the softer suspension travel - factor this into your driving habits. The improvement is most noticeable on trucks that frequently run empty or partially loaded.
