Air suspension for Harley Softail motorcycles improves ride comfort, handling, and customization by allowing adjustable ride height and damping. It replaces traditional coil springs with airbags, offering better load management and a smoother experience on uneven roads. This system is popular for riders seeking personalized performance and reduced vibration during long rides.

What Are the Benefits of Air Suspension for Harley Softail?
Air suspension provides adjustable stiffness, improved load capacity, and enhanced ride quality. Riders can fine-tune their bike’s height and damping for different road conditions or passenger loads. It reduces bottoming-out risks and offers a more stable feel during cornering compared to stock suspension systems.
How to Install Air Suspension on a Harley Softail?
Installation involves removing the factory shocks, mounting airbags, connecting air lines, and installing a compressor or manual fill system. Professional installation is recommended for proper calibration, though DIY kits with detailed instructions are available. Critical steps include ensuring airtight seals and testing pressure levels before full use.
For those attempting a DIY install, start by lifting the motorcycle securely using a hydraulic lift. Disconnect the battery to avoid electrical issues. Remove the stock shocks carefully, noting the orientation of mounting brackets. When positioning airbags, ensure they align with the frame’s mounting points to prevent uneven pressure distribution. Use threadlocker on bolts to secure components. Air lines should be routed away from heat sources like exhaust pipes, and connections must be checked with soapy water for leaks. A basic toolkit for installation includes:
How do I choose the right suspension?
| Tool | Purpose |
|---|---|
| Torque Wrench | Precise bolt tightening |
| Air Pressure Gauge | Monitoring PSI levels |
| Line Crimper | Securing air hose fittings |
After installation, test the system at low pressure (20–25 PSI) before gradually increasing to the recommended operating range. Calibrate the suspension by adjusting pressure while seated on the bike to account for rider weight.
Which Air Suspension Kits Are Best for Harley Softail Models?
Top-rated kits include Arnott Air Suspension, Slam Specialties Bags, and Air Ride Technologies systems. These offer durable construction, precise pressure control, and compatibility with Softail frames from 2000–2023 models. Kits with wireless remote controls and automatic leveling systems provide premium convenience for frequent riders.
Why Choose Air Suspension Over Traditional Coil Systems?
Air suspension outperforms coils in adjustability and adaptability, enabling real-time tweaks for cargo, passengers, or road surfaces. Unlike fixed-rate coils, air systems eliminate sagging over time and maintain consistent performance. They also enable dramatic stance adjustments for aesthetic customization without sacrificing ride quality.
Coil springs have a linear compression rate, which can feel too stiff or too soft depending on load changes. Air suspension, however, allows riders to increase pressure when carrying a passenger or decrease it for a smoother solo ride. This adaptability is particularly useful for touring enthusiasts who encounter varied terrain. Additionally, air systems reduce wear on other components like wheel bearings by evenly distributing weight. A comparison of key features:
| Feature | Air Suspension | Coil Springs |
|---|---|---|
| Adjustability | Dynamic PSI control | Fixed rate |
| Load Capacity | Up to 400+ lbs | ~300 lbs |
| Lifespan | 50,000–70,000 miles | 30,000–50,000 miles |
For riders prioritizing versatility, air suspension’s ability to switch between a lowered stance and higher ground clearance makes it ideal for both show bikes and daily riders.
How Does Air Suspension Affect Harley Softail Handling?
Properly tuned air suspension improves cornering stability by reducing body roll and maintaining tire contact. Over-inflation can create a harsh ride, while under-inflation may cause sluggish response. Balanced pressure settings enhance both straight-line comfort and aggressive lean angles, making it ideal for touring and spirited riding alike.
What Maintenance Does Harley Softail Air Suspension Require?
Monthly checks for air leaks, cleaning of compressors, and lubrication of moving parts are essential. Inspect air lines for cracks and replace O-rings every 2–3 years. Winter riders should use moisture traps to prevent internal corrosion. Professional servicing every 15,000 miles ensures optimal diaphragm integrity and valve function.
Routine maintenance starts with visual inspections. Look for worn bushings or misaligned airbags. Lubricate pivot points with silicone-based grease to prevent squeaking. Compressors should be kept free of debris—use an air filter if riding in dusty conditions. For cold climates, drain moisture from air tanks weekly to avoid freezing in lines. A sample maintenance schedule:
| Interval | Task |
|---|---|
| Monthly | Check PSI, inspect hoses |
| 6 Months | Lubricate fittings |
| Annually | Replace air filter |
If you notice uneven sagging or hear hissing noises, immediately check for punctured airbags. Carry a portable compressor for on-the-go adjustments during long trips.
Can Air Suspension Improve Harley Softail Load Capacity?
Yes—air suspension allows dynamic load adjustment by increasing pressure when carrying passengers or heavy luggage. Systems rated for 1,500+ lbs. GVWR can safely handle 400+ lb. loads without bottoming out, a 30% improvement over stock Softail suspensions. Always check manufacturer guidelines for maximum PSI limits during heavy-duty use.
Expert Views
“Modern air suspension systems revolutionize Softail customization,” says Alex Rivera, a Harley-Davidson aftermarket specialist. “Riders no longer need to choose between slammed aesthetics and functional comfort. With dual-channel compressors and smartphone integration, adjusting your bike’s stance is as easy as tapping an app—while maintaining the rugged reliability Harley enthusiasts expect.”
Conclusion
Harley Softail air suspension merges cutting-edge adjustability with classic cruiser performance. Whether prioritizing comfort, handling, or visual impact, these systems offer transformative benefits over stock setups. With proper installation and maintenance, riders can enjoy a tailored experience that adapts to every journey’s demands.
FAQs
- Does air suspension void Harley-Davidson warranties?
- Aftermarket suspension modifications may void powertrain warranties if improperly installed. Always use certified kits and professional installers to preserve frame-related coverage.
- How long do Harley air suspension bags last?
- Quality airbags typically last 50,000–70,000 miles. UV-resistant materials and rubber compounds prevent dry rot, but harsh climates may reduce lifespan by 20–30%.
- Can I install air suspension myself?
- Experienced mechanics can DIY install using pro-grade kits, but novices should seek professional help. Electrical components and pressure calibration require specialized tools for safe operation.
