A Harley air suspension kit replaces traditional coil springs with adjustable airbags, allowing riders to fine-tune their motorcycle’s ride height, stiffness, and comfort. This system improves handling, load capacity, and aesthetics while offering personalized adjustments for solo rides, passenger use, or heavy cargo. Popular brands like Arnott, Legend Suspensions, and Slam Specialties provide Harley-specific kits with advanced features like wireless controls and automatic leveling.
What Are the Core Benefits of Installing a Harley Air Suspension Kit?
Harley air suspension kits provide adjustable ride height, improved load management, and enhanced comfort. Riders can stiffen the suspension for cornering stability or soften it for long-distance comfort. The system automatically adjusts to weight distribution changes, preventing sagging when carrying passengers or luggage. Aesthetic customization is another key benefit, allowing motorcycles to sit lower at rest or lift for uneven terrain.
Beyond basic adjustments, these systems enable precise tuning for specific riding scenarios. For example, touring enthusiasts can raise the rear suspension by 1.5″ when pulling a trailer to maintain proper chassis alignment, while urban riders might prefer a 2″ drop for easier stops at traffic lights. The ability to store multiple presets (typically 3-5 configurations) means riders can switch between a stiff “sport mode” for twisty roads and a plush “cruise mode” for highway stretches within seconds. Recent advancements include smartphone integration, where apps display real-time pressure readings and suggest adjustments based on riding conditions.
How Do You Install a Harley Air Suspension Kit?
Installation involves removing stock shocks, mounting airbags, connecting air lines, and installing a compressor and control system. Kits like the Arnott Air Suspension Pro Series include pre-assembled components for bolt-on installation, while custom setups may require frame modifications. Professional installation is recommended for complex electrical integrations, though many riders with mechanical experience complete basic setups in 4-6 hours using manufacturer guides.
Can you use air suspension without a compressor?
Which Harley Models Are Compatible With Air Suspension Kits?
Most kits fit Touring models (Street Glide, Road King), Softail frames (Heritage Classic, Fat Boy), and Trike configurations. Model-specific variations exist—for example, Trike kits require reinforced airbags to handle rear axle torque. Always verify compatibility using manufacturer charts, as components like upper mounts and air line routing differ between Dyna, Sportster, and CVO models.
What Maintenance Does a Harley Air Suspension System Require?
Monthly checks for air leaks, compressor function tests, and annual air spring inspections are critical. Use only manufacturer-approved lubricants on air fittings. Cold climates demand moisture traps in air lines to prevent freezing. Systems with wireless controls need battery checks, as low power can cause calibration errors. Most kits include diagnostic LED indicators to simplify troubleshooting.
Regular maintenance should follow this schedule:
| Task | Frequency | Tools Required |
|---|---|---|
| Air pressure check | Every 500 miles | Digital gauge |
| Air line inspection | Monthly | Flashlight, soap solution |
| Compressor filter cleaning | Every 3 months | Compressed air |
Neglecting these tasks can lead to premature wear. A common issue is moisture buildup in air lines, which corrodes internal valves. Riders in humid climates should install aftermarket desiccant filters ($40-$80) to extend component life by 18-24 months.
How Does Air Suspension Affect Harley Warranty and Resale Value?
Factory warranties remain valid if installed by Harley-certified technicians using OEM kits. Aftermarket systems may void suspension-related warranties but often increase resale value by 7-12% when professionally documented. Buyers prioritize kits with service records and brand recognition. Retain stock parts for reinstallation if needed, as modified suspensions appeal only to specific markets.
What Are the Hidden Costs of Air Suspension Upgrades?
Beyond the $1,200-$3,500 kit cost, budget for installation ($300-$800), upgraded brakes ($200-$600 for heavy-duty calipers), and potential tire changes due to altered geometry. Premium controllers with presets add $150-$400. Insurance premiums may rise 5-10% unless riders provide installation certificates. Annual maintenance averages $120-$250 for seal replacements and compressor servicing.
Expert Views: Industry Insights on Air Suspension Trends
“The latest trend is integrated smart suspension—systems that sync with GPS to automatically adjust preload and damping based on road conditions. Riders want performance customization without manual tweaking. We’re also seeing demand for hybrid kits that combine air springs with electronic damping, offering 30% finer control than pure air systems.”

FAQ Section
- Does air suspension make Harleys safer?
- Yes—auto-leveling prevents bottoming out on bumps, and adjustable stiffness reduces fishtailing with heavy loads. However, improper installation can compromise safety.
- Can I install air suspension myself?
- Mechanically inclined riders can install basic kits, but electrical components (compressors, controllers) often require professional calibration to avoid system errors.
- How long do air suspension bags last?
- High-quality bags last 50,000-70,000 miles. UV exposure, extreme temperatures, and over-pressurization are primary causes of premature wear.
