What Is Air Ride Suspension on a Harley?
Air ride suspension replaces your factory rear shocks (and sometimes front components) with air-adjustable shocks. These shocks use compressed air instead of fixed springs, allowing you to raise or lower your Harley depending on load and riding conditions.
Benefits include:
Adjustable ride height
Smoother ride on rough roads
Better control when riding two-up
Improved comfort for long-distance touring
What You Need Before Installing Air Ride Suspension
Before starting, make sure you have:
Tools Required
Motorcycle jack or lift
Socket and wrench set
Torque wrench
Airline cutter or sharp blade
Zip ties
Thread locker
Parts Included in Most Air Ride Kits
Air shocks (rear or front & rear)
Air lines
Compressor or manual fill valve
Pressure switch or handlebar control
Mounting hardware
Always confirm the kit is compatible with your Harley model and year.
Step-by-Step: How to Install Air Ride Suspension on a Harley
Step 1: Secure the Motorcycle
Place your Harley on a motorcycle lift or jack so the rear wheel is slightly off the ground. This removes pressure from the rear shocks and makes removal easier.
Step 2: Remove the Stock Rear Shocks
Loosen the upper and lower shock bolts
Support the swingarm
Remove both factory shocks carefully
Keep the bolts if your air ride kit requires reuse.
Step 3: Install the Air Ride Shocks
Mount the air shocks in the same position as the stock shocks
Torque bolts to factory specifications
Ensure air fittings are facing the correct direction
Do not overtighten air fittings.
Step 4: Route the Air Lines
Cut air lines clean and straight
Route away from exhaust heat and moving parts
Secure with zip ties
Avoid sharp bends that may restrict airflow
Proper air line routing is critical for long-term reliability.
Step 5: Install the Compressor or Air Valve
Depending on your kit:
Mount the compressor under the seat or side cover
Or install a manual Schrader valve for hand inflation
Ensure electrical connections are secure if using a compressor.
Step 6: Connect Electrical Components (If Equipped)
Wire the compressor to the battery
Install switches or handlebar controls
Test power before final assembly
Always follow the wiring diagram provided by the manufacturer.
Step 7: Test for Air Leaks
Inflate the system slowly
Spray soapy water on fittings
Look for bubbles indicating leaks
Fix leaks before riding.
Step 8: Adjust Ride Height and Pressure
Set air pressure according to:
Rider weight
Passenger weight
Riding style
Most Harley air ride systems operate between 5–100 PSI, depending on load.
Common Mistakes to Avoid
Routing air lines near hot exhaust components
Overinflating air shocks
Skipping torque specs
Ignoring leak checks
Avoiding these mistakes extends the life of your air ride system.
Is Professional Installation Necessary?
Many Harley owners install rear air ride kits at home. However, professional installation is recommended if:
You’re installing a full front and rear system
Electrical wiring is involved
You’re unfamiliar with suspension work
