An air ride suspension kit for Harley Davidson enhances ride comfort, adjustability, and load management. It uses air springs to replace traditional coils, allowing riders to customize stiffness and height on-the-fly. This system improves handling, reduces vibration, and ensures optimal performance for touring, cruising, or heavy loads. Installation varies by model, but kits are designed for compatibility with most Harley bikes.
How do I choose the right suspension?
How Does an Air Ride Suspension Improve Harley Davidson Performance?
Air ride suspension replaces rigid coil springs with adjustable air bags, enabling real-time tuning for road conditions, passenger weight, or cargo. This reduces bottoming out, stabilizes cornering, and absorbs road imperfections. Riders can lower the bike at stops or raise it for uneven terrain, enhancing both aesthetics and functionality.
Advanced systems use pressure sensors to automatically adjust preload based on lean angles or acceleration forces. For example, when taking sharp turns, the suspension stiffens to prevent body roll, while highway cruising triggers a softer setting for reduced fatigue. This adaptability is particularly beneficial for two-up touring, where passenger weight distribution can shift dynamically. Modern kits also feature memory presets, allowing riders to save configurations for solo rides, group tours, or trailer-pulling scenarios.
What Are the Key Components of a Harley Air Ride Suspension Kit?
A typical kit includes air springs (front/rear), compressors, air tanks, pressure sensors, and a control module. Premium systems feature wireless remotes or smartphone apps for adjustments. Heavy-duty brackets, braided lines, and corrosion-resistant fittings ensure durability. Some kits integrate with existing ABS or traction control systems for seamless operation.

Which Harley Models Are Compatible with Air Ride Suspension Kits?
Most kits fit touring models like Road Glide, Street Glide, and Electra Glide. Softail and Dyna compatibility varies by year; post-2018 Softails often require custom brackets. Trike kits are available for Freewheeler and Tri Glide. Always verify fitment guides for your specific year, model, and frame type before purchasing.
How to Install an Air Ride Suspension Kit on a Harley Davidson?
Installation involves removing stock shocks, mounting air bags/compressors, routing air lines, and wiring the control system. Rear kits take 4-6 hours; full front/rear setups may require 8+ hours. Critical steps include calibrating pressure sensors, testing for leaks, and aligning the frame post-installation. Professional installation is recommended for integrated electronic systems.
Are Air Ride Suspensions Legal for Street Use on Harleys?
Most DOT-compliant kits are street-legal, but laws vary by state regarding minimum ride height and adjustable systems. States like California prohibit “dynamic” adjustments while moving. Static systems (pre-set before riding) are universally approved. Always check local regulations and ensure kits meet Federal Motor Vehicle Safety Standard (FMVSS) criteria.
What Maintenance Does a Harley Air Ride Suspension Require?
Monthly checks include inspecting air lines for cracks, testing compressor output, and lubricating o-rings. Drain moisture from air tanks quarterly. Winter riders should use antifreeze additives in pneumatic systems. Replace desiccant filters annually. Digital pressure gauges and leak detection apps help preempt failures.
Owners in humid climates should prioritize moisture management – trapped water can freeze in lines or corrode aluminum tanks. A maintenance schedule might include:
| Interval | Task |
|---|---|
| Every 1,000 miles | Check air pressure consistency |
| Every 3 months | Inspect fittings for leaks with soap solution |
| Annually | Replace compressor intake filters |
How Does Air Ride Compare to Coilover or Hydraulic Suspensions?
Air ride outperforms coilovers in adjustability and load capacity but requires more maintenance. Hydraulic systems offer similar customization but add weight and complexity. Air suspensions excel in long-distance comfort, while coilovers are preferred for track performance. Cost-wise, air kits start at $1,500 vs. $800+ for premium coilovers.
The key advantage emerges in load management – air systems can compensate for 300+ lb payload changes instantly, whereas coilovers need manual preload adjustment. However, hydraulic suspensions provide faster response times for aggressive riding. For riders prioritizing multi-surface adaptability, air systems dominate:
| Feature | Air Ride | Coilover |
|---|---|---|
| Adjustment Range | 3-6 inches | 1-2 inches |
| Weight Capacity | Up to 1,200 lbs | Up to 800 lbs |
| Installation Complexity | High | Moderate |
“Modern air ride systems have transformed Harley touring bikes into luxury cruisers. With advancements in Bluetooth controls and self-leveling tech, riders no longer sacrifice reliability for comfort. However, choosing kits with aircraft-grade aluminum tanks and dual compressors is critical—cheap units can’t handle repeated heat cycles.” – Senior Engineer, Leading Aftermarket Suspension Brand
FAQ
- Does air ride suspension affect Harley Davidson warranty?
- Aftermarket suspensions may void factory warranties if installed improperly. Use Harley-approved kits or certified technicians to preserve coverage. Document all modifications and ensure components meet OEM specifications.
- Can I install air ride myself?
- Mechanically inclined riders can install basic kits using manufacturer guides. However, electronic systems (compressors/wiring) require professional calibration. Always torque bolts to factory specs and validate frame alignment post-installation.
- How long do air ride suspensions last?
- Quality kits last 50,000+ miles with proper maintenance. Air bags typically fail before compressors; inspect for UV damage and ozone cracking. Desert or coastal riders should expect shorter lifespans due to extreme temps and salt exposure.
