4. Installation Instructions
Important Safety Notice: All modifications must be installed by qualified personnel and in compliance with your local modification regulations. Improper installation can lead to vehicle damage or personal injury.
The kit is designed for quick and efficient screw-on installation, eliminating the need for additional accessories. Follow these general steps:
- Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and block the wheels. Lift the rear of the vehicle using a suitable jack and support it with jack stands.
- Remove Existing Components (if necessary): Depending on your vehicle's current setup, you may need to remove existing bump stops or other components to make space for the air springs.
- Mount the Brackets: Attach the mounting brackets to the vehicle's chassis and axle using the provided fastening screws. Ensure all bolts are tightened to the manufacturer's specifications.
- Install Air Springs: Position the air springs between the upper and lower mounting brackets. Secure them using the provided hardware.
- Connect Air Lines: Cut the 10m air hose to the required lengths. Connect one end of the air hose to the air fitting on each air spring and the other end to the air fittings at your desired inflation point (e.g., bumper, chassis). Ensure all connections are secure and leak-free.
- Test for Leaks: Inflate the air springs to a low pressure (e.g., 10-20 PSI) and check all connections for air leaks using a soapy water solution. Bubbles indicate a leak.
- Final Checks: Lower the vehicle, remove jack stands, and re-check all fasteners. Adjust air pressure as needed.

5. Operating Instructions
The air suspension kit allows for adjustable load support. Proper air pressure is crucial for optimal performance and safety.
- Inflation: Use an air compressor to inflate the air springs. Refer to your vehicle's and the air spring kit's specifications for recommended minimum and maximum air pressures. Do not exceed the maximum pressure.
- Load Adjustment:
- For heavy loads or towing, increase air pressure to maintain a level vehicle stance and improve stability.
- For lighter loads or unladen driving, reduce air pressure to improve ride comfort.
- Monitoring: Regularly check the air pressure in the springs, especially before and during long trips or when carrying varying loads.
- Driving Conditions: Adjust air pressure according to road conditions and load. Higher pressure may be beneficial for rough terrain or heavy loads, while lower pressure is suitable for smooth roads.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your air suspension kit.
- Inspect Air Springs: Periodically inspect the air springs for any signs of wear, cracks, punctures, or damage. Check for proper seating and alignment.
- Check Air Lines and Fittings: Examine air lines for kinks, abrasions, or leaks. Ensure all air fittings are tight and free from corrosion.
- Clean Components: Keep the air springs and surrounding components clean from dirt, debris, and road salt, which can accelerate wear.
- Pressure Checks: Maintain recommended air pressure levels. Avoid operating the air springs completely deflated or over-inflated for extended periods.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Air spring not holding pressure | Leak in air line, fitting, or air spring itself. | Check all connections with soapy water for bubbles. Tighten fittings or replace damaged components. Inspect air spring for punctures. |
| Uneven vehicle height | Unequal air pressure in springs, uneven load distribution. | Check and adjust air pressure in each spring individually. Redistribute load if possible. |
| Excessive vibration or harsh ride | Over-inflation, improper installation, worn vehicle suspension components. | Reduce air pressure to recommended levels. Re-check installation. Inspect other suspension components. |
