Before purchasing or installing this product, it is crucial to verify its compatibility with your vehicle. The most common mistake is buying an air bag solely by make and model. Always consult your dealer and ask for the correct part number for your vehicle, ideally with your Vehicle Identification Number (VIN).

Alternatively, carefully compare the specifications and diagrams provided in this manual with your existing air bag to ensure all dimensions and mounting points match precisely. Using an incorrect air bag can lead to premature failure, potentially causing a serious accident.

5. Installation Guidelines (Setup)

Installation of air spring bags should ideally be performed by a qualified mechanic or technician with experience in heavy-duty vehicle suspension systems. Incorrect installation can lead to system malfunction, damage to the air spring, or safety hazards.

General Steps (Consult Service Manual for Specifics):

1. Safety First: Park the vehicle on a level surface, engage parking brakes, and use appropriate jack stands to support the vehicle frame. Ensure the air suspension system is fully depressurized.
2. Remove Old Air Spring: Disconnect air lines and mounting hardware. Carefully remove the old air spring, noting its orientation and any shims or spacers.
3. Inspect Mounting Surfaces: Clean and inspect the upper and lower mounting surfaces for damage, corrosion, or debris. Repair or replace as necessary.
4. Install New Air Spring: Position the new TORQUE TR9580 air spring, ensuring proper alignment with mounting holes. Secure with new or appropriate hardware, tightening to manufacturer's torque specifications.
5. Connect Air Lines: Reconnect air lines, ensuring a secure, leak-free connection.
6. Inflate and Test: Slowly reinflate the air suspension system to the recommended pressure. Check for air leaks using a soapy water solution. Lower the vehicle and perform a functional test, checking for proper ride height and stability.

Refer to your vehicle's specific service manual for detailed, step-by-step installation instructions and torque specifications.

6. Operation

The TORQUE Trailer Air Spring Bag operates as a pneumatic suspension component, supporting the vehicle's load and providing a smooth ride by absorbing road shocks. Proper operation relies on maintaining the correct air pressure within the system.

• Maintain Proper Air Pressure: Always operate the air suspension system within the manufacturer's recommended pressure range. Over-inflation can lead to a harsh ride and premature wear, while under-inflation can cause bottoming out and damage to the air spring or vehicle components.
• Load Distribution: Ensure that the vehicle's load is distributed evenly to prevent excessive stress on individual air springs.
• Regular Monitoring: Periodically check the air pressure in your air springs, especially before long trips or when carrying heavy loads.

7. Maintenance

Regular maintenance is essential to ensure the longevity and optimal performance of your TORQUE air spring bags.

• Routine Inspection: Visually inspect the air springs regularly for signs of wear, cracks, abrasions, or air leaks. Check the condition of air lines and fittings.
• Cleaning: Keep the air springs clean and free from dirt, debris, and corrosive substances. Use mild soap and water for cleaning.
• Check Mounting Hardware: Periodically check that all mounting bolts and nuts are securely tightened to the manufacturer's specifications.
• Avoid Over-Extension/Compression: Ensure that the suspension system's travel limits are properly set to prevent the air springs from over-extending or bottoming out, which can cause damage.

8. Troubleshooting

If you experience issues with your air spring system, consider the following common troubleshooting steps:

• Air Leakage: If an air spring loses pressure, check all air line connections, fittings, and the air spring itself for leaks using a soapy water solution. Bubbles indicate a leak.
• Improper Ride Height: Verify that the air pressure is within the recommended range. Check the leveling valve (if applicable) for proper operation and adjustment.
• Uneven Ride: This could indicate an issue with one air spring, an air line, or a leveling valve. Check each component individually.
• Excessive Vibration/Noise: Inspect the air spring and surrounding components for loose mounting hardware, contact with other parts, or internal damage to the air spring.

For complex issues, it is recommended to seek assistance from a professional mechanic.
