Frequently Asked Questions About Peterbilt 567/579 Front Axle Air Ride Kits

Will these air ride kits fit my specific Peterbilt 567 or 579 model year?

Our front axle air ride kits are designed to fit Peterbilt 567 and 579 models from 2013 to present. However, compatibility can vary based on your truck's specific configuration, including axle weight rating and existing suspension setup. We recommend checking your truck's VIN and current suspension specifications before ordering. If you're unsure, our tech support team can help verify fitment at 1-800-875-3701.

What's the typical installation time and do I need special tools?

Professional installation typically takes 4-6 hours depending on your experience level and truck configuration. You'll need standard shop tools including air tools, torque wrenches, and jack stands rated for commercial vehicles. Some installations may require minor drilling or bracket modifications. Many customers report that having a second person helps significantly with alignment during installation. We provide detailed installation instructions with each kit, and installation support is available if you run into issues.

How much will this improve my ride quality and what's the real-world difference?

Drivers typically report a 40-60% improvement in ride quality, particularly noticeable on rough roads and expansion joints. The air ride system absorbs shock and vibration that would normally transfer directly through leaf springs to the cab. This translates to less driver fatigue on long hauls, reduced cab shake, and better protection for sensitive cargo. The system also helps maintain consistent ride height regardless of load weight.

What maintenance is required and how long do these kits typically last?

Air ride kits require minimal maintenance beyond regular visual inspections for air leaks and checking air pressure settings. Most drivers check their systems during pre-trip inspections. The air bags typically last 200,000-300,000 miles under normal conditions, while compressor and valve components can last the life of the truck with proper maintenance. We recommend keeping spare air line fittings on hand as these are the most common wear items.

Can I adjust the ride height and stiffness, and will this affect my truck's handling?

Yes, these kits feature adjustable air pressure settings that allow you to fine-tune both ride height and stiffness to match your load and driving preferences. Most systems include in-cab controls for easy adjustment. Properly adjusted, the air ride system can actually improve handling by maintaining optimal suspension geometry. The key is setting appropriate pressure ranges for your typical loads - we include recommended pressure charts based on axle weight with each kit.
