5.3 Air Line Connection
- Route the air line from the air springs to a convenient location for the inflation valves, avoiding sharp edges, heat sources, and moving parts.
- Cut the air line to the appropriate length and connect it to the air springs and inflation valves using the provided fittings. Ensure all connections are secure and leak-free.
- Install the inflation valves in an accessible location, such as the bumper or fender well.
5.4 Post-Installation Check
- Reinstall the wheels and lower the vehicle.
- Inflate the air springs to approximately 20-30 PSI.
- Check for any air leaks using a soapy water solution on all connections. Bubbles indicate a leak.
- Verify proper clearance around all components, ensuring no rubbing or interference.
6. Operation
The maXpeedingrods air suspension kit allows for adjustable air pressure to optimize your vehicle's ride height and load support.
6.1 Adjusting Air Pressure
- Minimum Pressure: Always maintain a minimum of 5 PSI in the air springs, even when the vehicle is unloaded. This prevents damage to the air springs.
- Maximum Pressure: Do not exceed 100 PSI.
- Load Leveling: Inflate the air springs to achieve a level ride height when carrying heavy loads or towing. This helps to restore proper steering, braking, and headlight aim.
- Ride Comfort: Adjust pressure within the recommended range to achieve desired ride comfort and stability based on road conditions and load.

7. Maintenance
Regular inspection and maintenance will prolong the life of your air suspension system.
- Monthly Inspection: Check air lines and connections for wear, cracks, or leaks. Ensure all mounting hardware is secure.
- Cleanliness: Keep the air springs free from dirt, debris, and corrosive materials.
- Pressure Check: Periodically check and maintain the recommended air pressure (5-100 PSI).
8. Troubleshooting
If you encounter issues with your air suspension kit, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Air Leak | Loose fittings, damaged air line, punctured air spring | Check all connections with soapy water. Tighten fittings. Inspect air lines and air springs for damage. Replace damaged components. |
| Uneven Ride Height | Unequal air pressure in bags, uneven load distribution | Check and adjust air pressure in each bag individually. Redistribute load evenly. |
| Air Springs Not Inflating | Blocked air line, faulty inflation valve, severe leak | Inspect air lines for kinks or blockages. Check inflation valve for proper function. Check for major leaks. |
If problems persist after attempting these solutions, contact maXpeedingrods customer support.
