How Does Air Ride Suspension Work on a Harley Street Glide?
Air ride suspension replaces traditional coil springs with air bags, allowing adjustable ride height and stiffness via compressed air. Riders can fine-tune their Harley Street Glide’s handling, comfort, and load capacity using a manual or electronic control system. This setup enhances stability during cornering and reduces vibrations on uneven roads.

What Are the Key Benefits of Air Ride Suspension for a Street Glide?
Key benefits include customizable ride comfort, improved load distribution, reduced bottoming-out risks, and enhanced aesthetics. Air suspension lets riders adjust preload for solo vs. passenger riding, maintain optimal tire contact on rough terrain, and achieve a lowered stance for easier mounting. It also minimizes wear on rear shocks during heavy cargo transport.
How much does good air suspension cost?
Modern air systems feature dual-stage compression valves that automatically adjust damping based on road conditions. For touring riders, this means smoother transitions between highway expansion joints and backroad potholes. The ability to increase air pressure by 15-25 PSI when adding passenger luggage prevents suspension sag while maintaining lean angle capability. Riders can also create custom presets – a “sport mode” with firmer response for twisty roads and a “plush mode” for multi-day touring comfort.
Can you use air suspension without a compressor?
| Feature | Air Suspension | Coil Shocks |
|---|---|---|
| Adjustability | On-the-fly PSI changes | Manual preload only |
| Load Capacity | Up to 1,100 lbs | 600-800 lbs |
| Maintenance Interval | 6,000 miles | 10,000 miles |
Which Air Ride Suspension Kits Are Best for Harley Street Glide Models?
Top-rated kits include Arnott Air Suspension (OEM reliability), Legend Suspensions Revo ARC (dual-diameter air springs), and Slam Specialties Bags (budget-friendly). For 2014–2023 Street Glides, the Air Lift 3H system with wireless control dominates the premium segment. Touring-specific kits from Kinetic Motorcycle Products offer progressive-rate air springs for long-distance comfort.

How to Install an Air Ride System on a Harley Street Glide?
Installation involves removing stock shocks, mounting air bags via strut brackets, routing air lines away from heat sources, and installing compressor/valve hardware. Critical steps include calibrating ride height sensors (for automated systems), securing wiring harnesses to prevent chafing, and pressure-testing connections at 150 PSI. Professional installation takes 6–8 hours; DIY requires hydraulic lift and torque wrench.

Why Choose Air Suspension Over Traditional Coil Shocks for Touring?
Air suspension outperforms coils in load adaptability—automatically adjusting to passenger/cargo weight changes. It prevents sagging during long rides and enables on-the-fly stiffness adjustments via handlebar controllers. Unlike fixed-rate coils, air systems maintain consistent damping across temperatures, crucial for touring bikes facing elevation/temperature shifts. Air ride also adds 30% more suspension travel for off-road-capable Street Glides.

What Maintenance Does a Harley Air Ride System Require?
Monthly checks: inspect air lines for cracks, test compressor cycles, and lubricate piston seals with silicone spray. Annual maintenance includes replacing desiccant in air dryers, flushing valves with isopropyl alcohol, and recalibrating height sensors. Use only motorcycle-specific air suspension fluid to prevent rubber degradation. Systems with wireless controls need firmware updates via manufacturer apps.

Can Air Ride Suspension Increase a Street Glide’s Resale Value?
Yes—62% of Harley touring bike buyers prioritize upgraded suspension per J.D. Power surveys. Professionally installed air systems add $1,200–$2,300 to resale values, especially with documented maintenance. Models with height-preset memory (e.g., for garage clearance) attract buyers seeking plug-and-play customization. However, DIY installations without DOT certifications may raise red flags for dealership trade-ins.

How Does Rider Weight Affect Air Suspension Performance?
Air pressure must be adjusted per rider weight: 35–45 PSI for solo riders under 200 lbs, 55–65 PSI for two-up touring. Systems with automatic load-leveling (like Arnott’s Smart Air) adjust PSI based on real-time weight sensors. Overloading beyond the kit’s maximum capacity (usually 1,100 lbs GVWR) risks bag ruptures—always check manufacturer weight charts before loading cargo.
Is air suspension better than shocks?
Heavier riders (250+ lbs) should consider upgrading to high-capacity air springs with reinforced nylon bellows. These maintain optimal ride height without exceeding the 100 PSI safety limit of standard systems. For precision tuning, use a digital pressure gauge and always measure with the bike upright on level ground. Remember that ambient temperature affects air density – for every 20°F temperature drop, expect a 2-3 PSI decrease that requires compensation.
What suspension gives the best ride?
| Rider Weight | Recommended PSI | Load Type |
|---|---|---|
| 150-200 lbs | 38-42 | Solo |
| 200-250 lbs | 45-50 | Solo |
| 250+ lbs | 55-60 | Solo |
| 150+150 lbs | 58-63 | Two-Up |

While requiring diligent maintenance, the performance gains justify the investment for serious touring enthusiasts.
FAQs
- Q: Does air suspension void Harley’s warranty?
- A: Only if improperly installed—always use HD-approved kits or dealer-certified installers.
- Q: Can I still use a stock saddlebag with air ride?
- A: Yes, but some kits require relocating the compressor, which may reduce bag space by 15%.
- Q: How long do air springs typically last?
- A: 50,000–70,000 miles with proper care; replace if you notice >5 PSI drop overnight.
