Frequently Asked Questions About International WorkStar Front Axle Air Ride Kits

What model years of International WorkStar trucks are compatible with these front axle air ride kits?

Our front axle air ride kits are designed to fit International WorkStar models from 2008 through 2017. These kits are specifically engineered for WorkStar 7300, 7400, 7500, and 7600 series trucks. Before ordering, verify your truck's exact model year and series number, as mounting points and axle configurations can vary between model years. If you have a 2018 or newer WorkStar, contact our support team as these may require different kit configurations.

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

Installation typically takes 4-6 hours for experienced mechanics and requires standard shop tools including impact wrenches, jack stands rated for commercial trucks, and basic hand tools. The most challenging aspect is properly setting the ride height and ensuring correct air line routing. While many owner-operators successfully install these kits themselves, we recommend professional installation if you're unfamiliar with air suspension systems. Each kit includes detailed instructions with diagrams, and installation hardware is included. You'll need access to the truck's existing air system for connection.

What's the actual weight capacity and durability of these air ride kits?

Our front axle air ride kits are rated for standard WorkStar front axle capacities ranging from 12,000 to 20,000 pounds depending on your specific axle model. The air springs themselves are constructed with reinforced rubber and steel components designed to handle continuous commercial use. Based on customer feedback, these kits typically last 200,000-300,000 miles with proper maintenance. The most common wear items are the air bags themselves, which can be replaced individually without replacing the entire kit.

Will adding a front air ride kit affect my truck's warranty or DOT compliance?

Installing an aftermarket air ride kit will not void your truck's factory warranty as long as installation is performed correctly and doesn't damage other components. These kits are DOT compliant and meet FMVSS standards for commercial vehicles. However, you must ensure proper installation and maintain correct ride height to remain compliant. Some states require inspection after suspension modifications, so check your local regulations. We provide all necessary documentation for compliance verification.

What maintenance is required, and what are common issues to watch for?

Regular maintenance includes checking air pressure weekly, inspecting air lines for leaks or damage during pre-trip inspections, and draining moisture from the air system daily. Common issues reported by users include air leaks at fittings (usually from improper installation), air bag wear after 150,000+ miles, and height sensor adjustments needed after heavy use. Keep spare air line fittings on hand as these are the most frequent maintenance items. The complete system should be professionally inspected every 50,000 miles or annually.
