Kenworth Air Glide Suspension improves ride quality by using air springs to absorb road shocks, reduce vibration, and maintain consistent load distribution. This system enhances driver comfort, protects cargo from damage, and minimizes wear on vehicle components, making it ideal for long-haul trucking and heavy-duty applications.
How do I choose the right suspension?
What Maintenance Practices Extend Air Glide Suspension Lifespan?
Regularly inspect air springs for leaks, clean debris from suspension components, and check air compressor functionality. Monitor ride height valves monthly and replace air dryer cartridges annually. Proper alignment checks every 50,000 miles prevent uneven wear. Use only OEM-recommended air pressure settings to avoid overstress.
Proactive maintenance includes using infrared thermometers to detect abnormal heat patterns in air bags, which often precede visible damage. Fleet managers should document pressure readings during load changes – consistent deviations over 3 PSI may indicate valve issues. For winter operations, installing heated purge lines prevents moisture buildup in air circuits. A common oversight is neglecting the slider rail lubrication on tandem axle models, which requires synthetic grease applications every 15,000 miles.
| Component | Service Interval | Key Tool |
|---|---|---|
| Air Dryer | 12 Months | Desiccant Tester |
| Height Valves | 6 Months | Digital Level |
| Mounting Bolts | 100k Miles | Torque Wrench (250 ft-lbs) |
How Does Air Suspension Impact Cargo Security?
The system’s constant load-leveling prevents cargo shifts during sudden stops or turns. Integrated roll stability features reduce tip-over risks by 40% compared to spring suspensions. Temperature-resistant air bags maintain performance in extreme conditions (-40°F to 200°F), crucial for sensitive shipments like pharmaceuticals.
Is air suspension better than shocks?
Advanced models now incorporate load spectrum sensors that analyze cargo distribution in real time. These systems automatically adjust air pressure asymmetrically – for example, increasing left-side stiffness when cornering with high-center loads. During emergency braking, the suspension firms up rear bags within 0.8 seconds to counter dive forces. Third-party testing shows air-suspended trailers experience 58% fewer load shift incidents than spring equivalents when navigating switchbacks.
| Scenario | Air Suspension | Spring Suspension |
|---|---|---|
| 60 MPH Emergency Stop | 1.2″ Forward Shift | 4.7″ Forward Shift |
| 30° Banked Turn | 0.5° Tilt | 2.3° Tilt |
| Railroad Crossing | 12 G Vertical | 27 G Vertical |
