Frequently Asked Questions About Peterbilt 379 Front Axle Air Ride Kits

Will these air ride kits fit my specific year Peterbilt 379?

Most front axle air ride kits are designed to fit Peterbilt 379 models from 1987 to 2007. However, there can be variations based on your truck's original suspension configuration and front axle weight rating. We recommend checking your truck's VIN and front axle model number before ordering. If you're unsure, call us with your truck's specifications and we'll help you find the right kit.

How difficult is the installation process, and can I do it myself?

Installation typically takes 6-8 hours for an experienced mechanic or 10-12 hours for a skilled DIY installer. You'll need basic air tools, a good jack and jack stands, and experience with air brake systems. The most challenging parts are properly setting ride height and ensuring air lines are routed safely away from heat sources. Many customers choose professional installation to ensure proper alignment and avoid warranty issues. Installation instructions are included with each kit.

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

Drivers typically report a 60-70% reduction in cab bounce and vibration compared to stock leaf spring suspensions. The improvement is most noticeable on rough roads, expansion joints, and when running empty. Air ride provides better weight distribution and allows you to adjust pressure based on load conditions. Most operators find it significantly reduces driver fatigue on long hauls and extends the life of cab components.

What are the most common maintenance issues with these kits?

Air bags typically last 100,000-150,000 miles with proper maintenance. The most common issues are air leaks at fittings (check and retighten quarterly), moisture in the air system (drain tanks daily), and worn height control valve linkages (inspect every 6 months). Keep spare air line fittings and a repair kit in your truck. Most problems are minor and can be fixed roadside if you carry basic parts.

Are there different weight ratings available, and how do I choose?

Front axle air ride kits come in various weight ratings from 12,000 to 20,000 pounds. Your choice depends on your front axle GAWR (Gross Axle Weight Rating) found on your truck's certification label. Most 379s with standard single front axles use 12,000 or 14,000-pound kits, while heavy-haul applications may require 16,000 or 20,000-pound ratings. Using an under-rated kit will cause premature failure and void warranties.
