What Are the Core Benefits of Air Suspension for the Street Glide?
Air suspension offers adjustable preload, reduced bottoming-out risks, and 30% better load distribution compared to stock suspension. Riders report improved cornering stability and reduced vibration transfer, particularly on long rides. The system’s modular design allows incremental upgrades without full overhauls.
How do I choose the right suspension?
One often overlooked advantage is the ability to fine-tune ride characteristics for different terrains. Urban commuters might prefer a softer 35-45 PSI setting for pothole absorption, while highway riders could opt for 60-75 PSI to minimize body roll during lane changes. The system’s progressive-rate damping automatically adjusts compression based on impact severity – a feature stock shocks lack. This translates to 15-20% longer tire life due to reduced uneven wear patterns.
| Feature | Stock Suspension | Air Suspension |
|---|---|---|
| Adjustment Range | Fixed | 35-200 PSI |
| Load Capacity | 450 lbs | 620 lbs |
| Service Interval | 15,000 miles | 50,000 miles |
What Maintenance Does a Street Glide Air Suspension System Require?
Monthly inspections should check for air leaks using soapy water tests. Lubricate O-rings annually with PTFE-based grease. Replace air springs every 50,000 miles or if cracking exceeds 2mm depth. Compressor filters require cleaning every 3 months in dusty environments.
Seasonal maintenance is critical for optimal performance. During winter months, install insulated air line sleeves to prevent condensation freeze-ups below 32°F. Summer riders in desert climates should upgrade to brass fittings, which withstand thermal expansion better than aluminum. Always carry a portable 12V compressor – we recommend units with at least 1.5 CFM flow rate to handle emergency reinflation needs.
What suspension gives the best ride?
| Component | Maintenance Task | Frequency |
|---|---|---|
| Air Compressor | Filter cleaning | 3 months |
| Shock Absorbers | Bushing inspection | 6 months |
| Control Module | Software updates | Annual |
How to Install Aftermarket Air Suspension on a Street Glide?
Installation requires a lift kit, air compressor (6-8 gal recommended), and shock-specific brackets. Key steps include removing rear wheel, detaching stock shocks, mounting airbag assemblies, and routing air lines through frame cavities. Professional calibration using 100-150 PSI test cycles ensures optimal seal integrity before final adjustments.
How Does Air Suspension Compare to Coil and Hydraulic Systems?
Air systems provide 360-degree adjustability versus fixed-rate coils. They outperform hydraulic shocks in heat dissipation during sustained heavy loads, maintaining consistent damping up to 200°F. Weight savings average 11 lbs compared to premium coil-over alternatives.
What Are Common Air Suspension Issues in Street Glides?
Frequent issues include compressor burnout from moisture ingress (prevented with desiccant filters), solenoid valve failures (detectable through delayed response >0.8 sec), and air line chafing near swingarm pivot points. Error codes like “CF 881” indicate ECU communication faults requiring harness inspection.
Which Air Suspension Brands Are Best for Harley Street Glides?
Top-rated systems include Arnott Air (ISO 9001-certified, 5-year warranty), Slam Specialties (7075-T6 aluminum construction), and Air Lift Performance (app-controlled with 1000+ preset memory). Budget options like Universal Air offer partial compatibility but lack progressive-rate damping.
Expert Views
Modern air suspension transforms the Street Glide’s DNA. We’re seeing 40% adoption among touring riders – it’s no longer just for custom builds. The real innovation is in predictive load-leveling algorithms that adjust preload mid-corner.”

Conclusion
Upgrading to air suspension redefines the Street Glide’s capabilities, merging touring comfort with dynamic adjustability. While requiring precise installation and maintenance, the performance gains justify investment for serious riders. Emerging smart suspension tech promises even greater integration with Harley’s infotainment systems.
FAQs
- Does air suspension void Harley’s warranty?
- Only if installation damages OEM components. EPA-compliant systems preserve powertrain coverage per Magnuson-Moss Act guidelines.
- Can I retrofit air suspension to older Street Glide models?
- 2014+ models have direct-fit kits. Pre-2014 requires frame modifications costing $800-$1200.
- What PSI is safe for Street Glide air suspension?
- Never exceed 200 PSI. Optimal range is 35-75 PSI for solo riding, 85-110 PSI with passenger/luggage.
