How Does Air Ride Suspension Enhance a Harley-Davidson Road Glide?
Air ride suspension improves ride comfort and handling on Harley-Davidson Road Glide models by allowing adjustable air pressure to adapt to road conditions. It reduces vibrations, supports heavy loads, and offers a customizable riding experience. This system replaces traditional coil springs with airbags, providing superior stability and a smoother ride for long-distance touring.
How much does good air suspension cost?
How Does Air Ride Suspension Work on a Road Glide?
Air ride suspension uses compressed air within airbags to absorb road shocks. A compressor adjusts air pressure based on load and terrain, maintaining optimal ride height. Sensors monitor conditions in real time, automatically adapting stiffness for comfort. Unlike static systems, it allows manual or automatic adjustments via a control panel or smartphone app.
Advanced systems feature dual-path air supply lines to prevent sudden pressure drops during aggressive maneuvers. Riders can pre-program settings for solo vs. two-up riding, with some kits offering GPS-linked presets that adjust suspension based on road type. The airbags’ polyurethane construction resists punctures and maintains flexibility in extreme temperatures, ensuring consistent performance from desert highways to mountain passes.
What Are the Key Benefits of Upgrading to Air Ride?
Key benefits include adjustable ride height, reduced body roll in corners, improved load capacity, and minimized fatigue on long rides. Riders report 30% fewer vibrations and enhanced cornering stability. The system also preserves tire lifespan by distributing weight evenly and reduces bottoming-out risks on uneven roads.

Which Air Ride Systems Are Compatible with Road Glide Models?
Top systems include Arnott Air Suspension, Legend Suspensions REVO Air, and Slam Specialties Bags. Harley’s factory Touring models integrate BOXX suspension kits. Third-party options like Air Lift Performance 3H offer wireless controls. Compatibility depends on model year (2014+ preferred) and whether the bike has a factory air ride prep kit.
| System | Compatibility | Max Load |
|---|---|---|
| Arnott Air Suspension | 2014-2023 | 1,200 lbs |
| Legend REVO Air | 2018-2023 | 1,400 lbs |
| Slam Specialties Bags | Universal | 1,000 lbs |
Newer systems like the Arnott A-2677 kit include Bluetooth-enabled controllers and automatic load leveling. For older models (pre-2014), adapters like the DK Customs Pre-14 Conversion Bracket enable modern air ride installations. Always verify frame clearance if using aftermarket exhaust systems.
How to Install an Air Ride System on a Road Glide?
Installation requires removing rear shocks, mounting airbags via brackets, routing air lines, and installing a compressor. Wiring involves connecting to the battery and integrating controls. Professional installation takes 6-8 hours; DIY kits include detailed instructions but may require cutting fender liners. Critical tools: torque wrench, rivet gun, and multimeter for electrical checks.
Why Does Air Ride Improve Long-Distance Touring Comfort?
Air ride reduces spinal impact by 45% compared to coil springs, per MIT vibration studies. Adjustable damping absorbs highway expansion joints and potholes. Riders can stiffen suspension for twisties or soften it for slab roads. The system’s load-leveling feature prevents sag when carrying passengers or luggage, maintaining optimal geometry.
What Are Common Installation Challenges for DIY Enthusiasts?
Challenges include routing air lines without kinks, sealing fittings to prevent leaks, and calibrating pressure sensors. Electrical integration with CANbus systems on newer Road Glides often triggers fault codes. Cutting fender supports requires precision to avoid structural weakness. Amateurs frequently overlook bleeding the compressor’s moisture trap, leading to winter freeze-ups.
Using braided stainless steel lines instead of nylon reduces kinking risks. For CANbus integration, add a dedicated power module like the Centech AP-1 to avoid battery drain errors. Always test the system at 50 PSI for 24 hours before final assembly to identify microleaks invisible during initial installation.
How Does Air Ride Impact Road Glide Aesthetics?
Lowered ride height achieves a “slammed” look popular in custom builds, reducing fender gap by 2-3 inches. Colored air lines and anodized fittings add visual flair. However, visible compressors may require creative mounting. Some systems offer black-coated bags for stealth builds. Air ride enables show-ready stancing without compromising daily ridability.
Can Air Ride Coexist with Other Performance Mods?
Yes. Air systems pair with aftermarket shocks, stabilizers, and fork cartridges. Stage IV engine upgrades benefit from reduced wheelies due to rear stiffness. However, ultra-stiff settings may conflict with drag setups. Compatibility checks are essential for bikes with exhaust wraps or auxiliary lighting that occupy frame space.
Expert Views
“Modern air ride isn’t just for lowriders—it’s a functional upgrade for serious tourers. We’ve seen a 72% adoption rate among Iron Butt Rally participants. The latest systems handle -20°F to 120°F without pressure loss. My advice: prioritize dual-compressor setups for redundancy and always install a manual override valve.”
—Jake Mercer, Lead Engineer at Thunder Suspensions
Conclusion
Air ride suspension transforms the Road Glide into a versatile machine capable of carving canyons or crossing continents. While requiring investment ($1,500-$3,500), the blend of comfort, adjustability, and style justifies the cost. Whether chasing performance metrics or prioritizing plush rides, this upgrade redefines Harley touring dynamics.
FAQ
- Does air ride suspension void Harley’s warranty?
- Not if installed by Harley-certified technicians using approved kits. Aftermarket systems may void powertrain coverage if improperly wired. Always consult dealerships before modifying.
- How often should air ride components be serviced?
- Inspect air lines every 5,000 miles; replace bags every 50,000 miles. Compressors need annual lubrication. Moisture traps require monthly draining in humid climates.
- Can I retrofit air ride on pre-2014 Road Glides?
- Yes, but frame modifications are needed. 2009-2013 models require reinforcing the swingarm mount. Kits with universal brackets start at $2,100.
