Frequently Asked Questions About International ProStar Front Axle Air Ride Kits

What year models of International ProStar are these air ride kits compatible with?

Our front axle air ride kits are designed to fit International ProStar models from 2008 through 2017. However, compatibility can vary based on your specific truck configuration, including whether you have a set-forward or set-back front axle. We recommend checking your VIN or contacting our support team with your truck's specifics to ensure proper fitment before ordering.

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

Installation typically takes 4-6 hours for experienced mechanics and 6-8 hours for first-time installers. You'll need basic hand tools, air tools, jack stands, and a torque wrench. The most challenging part is usually removing the existing leaf spring setup and properly aligning the new air bags. Most kits include detailed instructions, but many customers recommend having a second person to help position components. Professional installation runs between $500-$800 at most shops.

What's the actual ride quality improvement I can expect?

Drivers typically report a 60-70% reduction in cab bounce and vibration, especially on rough roads. The air ride system absorbs road imperfections much better than leaf springs, reducing driver fatigue on long hauls. You'll notice the biggest improvement when running empty or with light loads, as the system maintains consistent ride height regardless of load. Many drivers also report less wear on steering components and reduced maintenance on cab interior parts due to less vibration.

Are these kits DOT approved, and will they affect my truck's warranty?

Yes, all our front axle air ride kits are DOT compliant and meet FMVSS standards. They won't void your truck's powertrain warranty, but they may affect suspension-related warranty claims if your truck is still under manufacturer warranty. We recommend checking with your dealer if you have remaining warranty coverage. The kits include all necessary documentation for DOT inspections and most states accept them without issue.

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

Air bags typically last 5-7 years or 500,000-700,000 miles with proper maintenance. You'll need to check air pressure weekly, inspect for leaks monthly, and keep the bags clean from road debris. The most common maintenance issue is small air leaks at fittings, which are easily fixed. Replacement air bags cost around $150-$250 each when needed. Overall maintenance is actually less intensive than traditional leaf springs, with no need for regular greasing or bushing replacements.
