Air suspension for the Harley-Davidson Road Glide improves ride comfort, load capacity, and handling by replacing stock shocks with adjustable air-filled chambers. It allows riders to customize stiffness and height for varying road conditions, passenger weight, or cargo loads. This upgrade reduces vibration, enhances stability, and provides a smoother long-distance touring experience.
What suspension gives the best ride?
What Are the Key Benefits of Installing Air Suspension on a Road Glide?
Air suspension systems on the Road Glide offer adjustable ride height, improved load distribution, and reduced rider fatigue. They enable on-the-fly adjustments via a wireless remote or smartphone app, adapting to solo rides, two-up touring, or heavy cargo. Enhanced cornering stability and reduced bottoming-out on rough roads are additional advantages, making it ideal for long-haul riders.
How Do You Install an Air Suspension Kit on a Harley Road Glide?
Installation involves removing the rear shocks, mounting air springs, connecting air lines, and installing a compressor. Most kits include detailed instructions, but professional installation is recommended for proper calibration. Critical steps include torqueing bolts to factory specs, testing for air leaks, and aligning the rear wheel to prevent handling issues.
Which Air Suspension Brands Are Most Compatible with the Road Glide?
Top brands include Arnott Air Suspension, Legend Suspensions, and Slam Specialties. These brands offer model-specific kits with reinforced brackets, heavy-duty airbags, and OEM-grade components. Compatibility varies between Road Glide generations (1998-2013 vs. 2014+), with some systems requiring additional mounting hardware for newer frame designs.
How do I choose the right suspension?
| Brand | Compatible Models | Key Features |
|---|---|---|
| Arnott | 2014+ Road Glide Ultra | Automatic leveling, 200 PSI capacity |
| Legend | 1998-2013 models | Dual airbags, progressive damping |
| Slam Specialties | All generations | Low-profile design, Bluetooth control |
Arnott’s systems excel in modern touring models with advanced load sensors, while Legend focuses on durability for older bikes. Slam Specialties stands out for riders prioritizing low-rider aesthetics without sacrificing functionality. All three brands recommend using nitrogen instead of compressed air to minimize moisture accumulation in the system, which is particularly important for riders in humid climates.
Why Should Riders Consider Load Capacity When Choosing Air Suspension?
Exceeding air suspension load limits risks premature wear or failure. Systems are rated for maximum PSI (typically 150-200 psi) and weight capacity (800-1,200 lbs). Riders carrying trailers or heavy luggage should opt for dual-bag systems with larger air volume. Always factor in combined rider/passenger/cargo weight when selecting components.
When Is the Best Time to Upgrade from Stock to Air Suspension?
Upgrade when experiencing bottomed-out shocks, sagging rear ends with passengers, or frequent long-distance touring. Stock suspension typically degrades after 20,000-30,000 miles. Air systems prove cost-effective for riders needing variable load capacity without permanent stiffening of the suspension setup.
Where Should You Position Air Compressors and Gauges on a Road Glide?
Mount compressors in waterproof areas like the tour pack or frame cavities. Digital gauges integrate with handlebar controls or wireless remotes. Avoid heat zones near engines or exhaust. Professional installers often use custom brackets behind saddlebags or under the seat to maintain aesthetics and accessibility.
| Location | Advantages | Considerations |
|---|---|---|
| Tour Pack | Easy access, protected from debris | Reduces luggage space |
| Frame Cavity | Stealthy installation, balanced weight | Requires custom brackets |
| Under Seat | Short air line routing | Limited to smaller compressors |
Riders in rainy climates should prioritize sealed compartments, while those in dusty regions need to install additional air filters regardless of placement. The compressor’s orientation matters—horizontal mounting prevents oil pooling in vertical setups. Always leave at least 1″ clearance around the compressor for heat dissipation during extended use.
Expert Views
“Modern air suspension transforms the Road Glide from a cruiser to a true mile-eater. The latest systems automatically adjust pressure based on lean angles and acceleration forces, rivaling premium car suspensions. However, riders must maintain proper tire pressure—air suspension can’t compensate for underinflated tires.” – John Mercer, Lead Engineer at Ironborne Suspensions
Conclusion
Air suspension elevates the Harley Road Glide’s performance through customizable damping, improved load management, and reduced rider fatigue. While requiring careful installation and maintenance, it’s a game-changer for touring enthusiasts seeking comfort and adaptability across diverse riding conditions.
FAQs
- Does Air Suspension Void Harley-Davidson Warranties?
- It may void suspension-related warranties if improperly installed. Use Harley’s Screamin’ Eagle air suspension or certified third-party kits installed by authorized dealers to maintain coverage.
- Can You Adjust Air Suspension While Riding?
- Yes, advanced systems like AirFX Pro allow real-time adjustments via handlebar controllers. However, avoid extreme pressure changes mid-corner to prevent handling instability.
- How Often Should Air Suspension Be Serviced?
- Inspect seals every 10,000 miles, replace air springs every 50,000 miles, and flush moisture from compressors annually. Use synthetic lubricants on o-rings to prevent dry-rot in humid climates.
