What Are the Key Components of a Street Glide Air Suspension System?
A Street Glide air suspension system includes airbags, compressors, valves, and a control module. Airbags replace stock shocks, compressors maintain pressure, and valves adjust airflow. Advanced kits feature wireless remotes or smartphone apps for real-time adjustments. High-quality lines and fittings ensure durability, while pressure sensors prevent over-inflation, maintaining optimal performance and safety.
What suspension gives the best ride?
Modern air suspension systems employ reinforced rubber airbags with multi-ply construction to withstand up to 300 PSI. The compressor unit typically features a moisture trap to prevent corrosion in air lines, while dual solenoid valves enable independent front/rear pressure adjustments. Premium kits include CANbus-compatible control modules that integrate with the motorcycle’s existing electronics, allowing preset ride height configurations for different scenarios like highway cruising or parking.
| Component | Function | Lifespan |
|---|---|---|
| Air Springs | Replace coil springs, provide adjustable support | 50,000-75,000 miles |
| Digital Controller | Manages pressure settings and presets | 5-7 years |
| Air Compressor | Maintains system pressure | 3-5 years |
What Maintenance Practices Extend Air Suspension Lifespan?
Regularly inspect air lines for leaks, clean debris from airbags, and lubricate moving parts with silicone spray. Check compressor filters monthly and replace them annually. Avoid over-inflation by monitoring pressure gauges, and store the bike covered to prevent UV damage to rubber components. Annual professional inspections ensure seals and electrical connections remain intact.
Seasonal maintenance is crucial – winter riders should install air line heaters to prevent moisture freeze-ups. Use dielectric grease on all electrical connections during biannual servicing. For airbag care, apply UV protectant to exposed rubber surfaces every 90 days. Riders in coastal areas should rinse components with distilled water after saltwater exposure. Always maintain 15-20 PSI in the system during storage to prevent airbag membrane fatigue.
Is air suspension better than shocks?
| Maintenance Task | Frequency | Tools Required |
|---|---|---|
| Air Line Inspection | Every 1,000 miles | Leak detection spray |
| Compressor Filter Change | Annually | Replacement filter, screwdriver |
| Full System Diagnostic | Every 5,000 miles | Digital pressure gauge, multimeter |
Expert Views
“Air suspension transforms the Street Glide from a rigid cruiser to a adaptable touring machine,” says a Harley-Davidson aftermarket specialist. “Modern kits integrate seamlessly with CANbus systems, letting riders toggle between pre-set modes—like ‘sport’ or ‘tour’—without manual tweaks. The key is balancing air pressure with spring rates; too stiff, and you lose comfort; too soft, and handling suffers.”
Conclusion
Air suspension systems for the Harley Street Glide offer unmatched adjustability, comfort, and style. Whether prioritizing long-distance comfort, performance handling, or aesthetic customization, these systems provide a transformative upgrade over stock suspensions. Regular maintenance and professional installation ensure longevity, making them a worthwhile investment for serious riders.
FAQ Section
- Does air suspension affect Harley Street Glide’s warranty?
- Aftermarket installations may void warranties if they cause damage. Use certified kits and professional installers to avoid issues.
- How much weight can air suspension support?
- Premium kits handle up to 1,200 lbs, accommodating riders, passengers, and cargo without sagging.
- Is air suspension suitable for off-road use?
- While durable, air systems are designed for paved roads. Rough terrain risks puncturing airbags or damaging compressors.
