Frequently Asked Questions About International S1700-S1900 Front Axle Air Ride Kits

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

These air ride kits are designed to fit International S1700, S1800, and S1900 models typically manufactured from the late 1980s through early 2000s. However, compatibility can vary based on your truck's specific front axle configuration and GAWR (Gross Axle Weight Rating). Before ordering, check your truck's door jamb sticker for the axle model number and weight rating, or contact us with your VIN for verification. Most kits accommodate standard 12,000-14,000 lb front axles, but some modifications may be required for heavier-duty configurations.

How difficult is the installation process, and what tools or modifications 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. Most kits bolt directly to existing mounting points without frame modifications. However, you'll need to route air lines, install the height control valve, and may need to relocate or modify the shock mounts depending on your specific truck configuration. Professional installation is recommended if you're not comfortable working with air systems or suspension components. Budget an additional $500-800 for professional installation at most shops.

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

A complete front axle air ride kit typically includes air springs, mounting brackets, height control valve, air line fittings, and detailed installation instructions. However, you may need to purchase separately: DOT-approved air lines (usually 20-30 feet), air tank if your truck doesn't have rear air suspension, pressure protection valve, and new shocks designed for air ride travel. Some customers also upgrade to manual dump valves for easier loading dock access. Verify what's included before ordering to avoid installation delays.

How much will this improve my ride quality, and what maintenance is required?

Customers typically report a 60-80% improvement in ride quality, with the most noticeable difference on rough roads and expansion joints. The air springs absorb road shock much better than steel leaf springs, reducing driver fatigue and cargo damage. Maintenance is minimal but important: check air pressure weekly, inspect air lines for wear every 3 months, and keep the height control valve linkage lubricated. Air springs typically last 100,000-150,000 miles with proper maintenance. Keep spare air line fittings on hand for emergency repairs.

What's the weight capacity, and how does it affect my truck's handling and load distribution?

Most kits maintain your truck's original front axle weight rating while providing adjustable ride height and improved load distribution. The air springs typically handle 12,000-14,000 lbs depending on the model. You can adjust air pressure to level the truck when loaded, improving tire wear and steering control. However, air ride won't increase your legal weight capacity beyond the axle's original rating. The system maintains 5-6 inches of ride height travel, and the height control valve automatically adjusts for load changes to maintain proper ride height.
